Vertical alignment this attribute defines the image vertical alignment according to the element area; the possible values are: Horizontal alignment this attribute defines the image horizontal alignment according to the element area; the possible values are: The evaluation time is a very interesting functionality and it is well explained in the JasperReports manual.

The possible values are: For the image element and for the text elements it is possible to visualize a frame or to define a particular padding for the four sides. It is a space between the element border and its content. Border and padding are specified in the border tab and they are properties that have been introduced from the JasperReports 0. It is possible to select type and colour of the border to draw for every side of the element. The border types are: A simple preview of the graphic effect produced by the selected border is visualized in the centre of the border tab.

Text elements Like the graphic elements, also the elements that allow to view the text have a common properties tab: In the font tab are set the properties of the text shown in the element, so not only the font dimension and type of the character , but also the text alignment, the eventual rotation and line space.

From it will be taken all the character properties; the presets fonts are defined at report level and it is possible to manage them by selecting the menu ViewReport fonts; Line spacing it is the interline value; the possible values are: The other characteristics of the font tab are explained in the chapter 6 which is completely dedicated to the Font. The text element properties can be modified also by using the text toolbar fig.

Static text The static text is used to show a non-dynamic text in the report. The only parameter that distinguishes this element from a generic text element is the static text tab where the text to view is specified: Text field A text field allows to print the value of a java expression.

The simplest case is the print of a string java. String coming from an expression like this: Hello World! In this case the result is exactly a static field created with a little bit more of work, because the string of the example is an expression of constant value; in reality the JasperReports does not directly associate the data to print to particular text elements like it happens in different tools of the report where the text element rappresents implicitly the value of a database field: At the same way for the images, an hypertextual link can be associated also to the textfields and it is defined by the HyperLink tab.

Textfield Expression Class it specifies the return type of the field expression; the possible values are many, they include all the java objects which comprehend the SQL types and some classes for the manage of the dates. In the following table all the selectable types are listed. Object java. Boolean java. Byte java. Date java. Timestamp java.

Time java. Double java. Float java. Integer java. InputStream java. Long java. Short java. BigDecimal java. String Table 5. In this list also the java. Object type is included. It can be used if no one of the other types is applicable to the associated data. JasperReports is able to format dates and numbers; the following tables summarize with some examples the letters and their meaning for the creation of patters of data and numbers.

Here there are some examples of formatting of dates and timestamp: Dates and Time Pattern Result "yyyy. Location Number Number Number Localized? Need not be quoted in prefix or suffix.

Separates positive and negative subpatterns. Multiply by and show as percentage Multiply by and show as per mille Currency sign, replaced by currency symbol. If doubled, replaced by international currency symbol. If present in a pattern, the monetary decimal separator is used instead of the decimal separator.

To create a single quote itself, use two in a row: Here there are some examples of formatting of numbers: Dates and Time Pattern Result " , 0. Thanks to the create button fig. Textfield Expression it is the expression that produces the value to print; it has to return an object of the same type declared in Textfield Expression Class; It is possible to transform a StaticText in a Textfield by selecting it and pressing the F3 key.

In order to change quickly the expression of one or more generic text elements, select them and press F2.

Subreport The subreport is an element that is able to contain in it an other report that is created starting from a jasper file and feed by a datasource that is specified in the subreport properties.

Following the subreport characteristics are briefly illustrated. However, because of the complexity of this subject, we will deeply explain the subreports in an another chapter.

Parameters Map Expression it identifies an expression which is valuated at runtime; the expression must return a java. Chart For all the details regarding the charts, see chapter Barcode This element allows to create and print dynamically a value in the form of barcode. The possible values are listed in table 5. Hyper Links The image and textfield elements can be used both as anchor into a document, and as hypertextual links towards external sources or other local anchor.

An anchor is a kind of label that identifies a specific position into the document. The hypertextual links and the anchors are defined by means of the Hyper Link tab fig. This is divided in two parts. In the superior part there is a text area through which it is possible to specify the expression that will be the name of the anchor.

This name can be referenced by other links. The inferior part is dedicated to the link definition towards an external source or a position into the document. JasperReports allows to create five types of hypertextual links: Through the Hyperlink target it is possible to specify if the exploration of a particular link has to be made into the current window it is the predefined setting and the target is Self , or into a new window Blank target.

Not all export formats support the hypertextual links. Reference The Reference link indicates an external source which is identified by a normal URL and it is ideal to point, in example, to a servlet to manage record drilldown functionalities. The only expression required is the Hypelink Reference Expression. LocalAnchor To point to a local anchor means to create a link between two locations into the same document. It can be used, for example, to link the titles of a summary to the chapters they refer to.

To define the local anchor it is necessary to specify the Hyperlink Anchor Expression which will have to produce an anchor valid name. LocalPage If instead of pointing to an anchor, you want to point to a specific current report page, it is necessary to create a LocalPage link.

In this case it is necessary to specify the pointed page number by means of the HyperLink Page Expression the expression has to return an Integer object. RemoteAnchor If you want to point to a particular anchor that is present in an external document, you will use the RemoteAnchor link.

In this case the URL of the pointed external file will have to be specified in the Hyperlink Reference Expression field and the name of the anchor will have to be specified in the Hyperlink Anchor Expression field. RemotePage This link allow to point to a particular page of an external document.

In this case too, the URL of the pointed external file will have to be specified in the Hyperlink Reference Expression field and the page number will have to be specified by means of the HyperLink Page Expression.

Fonts describe the characteristics shape and dimension of text.

In JasperReports it is possible to specify the font properties for each element. Moreover it is possible to define a set of global fonts named report font and associate them to an text element. This global font will then be used for the text contained in the element. The font Usually a font is defined by four basic characteristics: This is a string that specifies the name of the encoding to be used for the character coding. If the report is not exported to PDF format, the font used is the one specified in font name and enriched with the specified attributes.

Other attributes are ignored since they are inherented from the specified PDF font. In order to do this, it is necessary for the external fonts file with. It is necessary to avoid adding hundred's of TrueType fonts to the classpath because this slows down the start of iReport. In the Font name combo box only the system fonts, managed by the Java Virtual Machine, are shown and usually they are inherited by the operative system.

This means that if you want to select an external TTF font, to use in non-PDF reports, it is necessary to install it on your system before use. The combo box True Type font will be enabled. In it all the True Type fonts found in the classpath will be present.

Encoding The character encoding problem is one of the most obscure of JasperReports; in particular this problem occurs when you have to print in PDF format. So it is very important to choose the right PDF encoding for the characters.

The encoding specifies how the characters have to be interpreted: However some JVM versions do not support the encoding versions before 1. If you have some problems with reports of non-standard characters in PDF format, make sure that all the fields have the same encoding type and verify the charset used by the database from which the report data is read.

Use of Unicode characters It is possible to use the Unicode syntax in order to write non-standard characters such as the Greek, Cyrillic and Asian characters ; the Unicode code has to be specified in the expression that identifies the field text.

Report font To define a set of global fonts, select Report fonts from the View menu. This will open a window for managing the global fonts. The inserting scheme of a new global font is viewed in figure 6.

To use a global font in a textfield, select it from the Report font combo box figure 5. Limiting itself to set the property values of the selected report font to the selected element and to copy all the attributes of the global font to the text element. In fact the global fonts were born with the aim to economize the XML source, by avoiding having to specify all the font characteristics for every single field.

Since this work is completely automated in iReport, the optimizing has little importance. However, because of this, the attempt to centralize the report fonts managing is bypassed, because, if present, JasperReports uses the attributes specified at element level and they are always specified by iReport. More simply, if a global report font is used in a text element, its characteristics are saved with the text element and essentially overrides the global report font.

At the moment it is not possible to define a set of fonts to be used in more than one report. These objects are used in the expressions, they can change their value during the print progression and they are typed, that is all these objects have a type which correspond to a java class such as String or Double.

Fields, parameters and variables have to be declared in the report in order to be used. By selecting from the main menu View we find, among the others, the Report fields that is the fields , Report variables and Report Parameters submenus.

Each of these three submenus allows us to view the window for managing all these objects figure 7. Through this window it is possible to declare, modify and remove fields, variables and parameters. Fields A print is commonly created starting from a data source: In order to declare a field, press the new button and a window as in figure 7. The fields are identified by a name, by a type and by a facultative description. It is not possible to choose the field type in an arbitrary way. If the field type is not present among the predefined types, it is possible to declare the field as java.

Object and cast it to the required type in the expressions where the field is used. In an expression you can refer to a field by using the syntax: Person object, write: The number of fields in a report could be really high also reaching reaching the hundreds. For this reason in iReport different tools exist for the declaration of fields retrieved by particular datasources typologies. Registration of fields of a SQL query The most widely used tool is the one which allows us to declare or record the fields of a SQL query in order to use them in a report.

To do this it is necessary first of all to open the ReportQueryDialog pressing the button. The window for the query definition will appear. It will be used to fill the report if the report is really created starting from a SQL query. After being sure that the connection to the DBMS is active go to page 15 to see how to do it , insert a query, for example: By selecting the fields, they will be registered in the values window fig.

To register the fields, it is necessary to select them from the list; if the query contains some mistakes, deselect the Automatically Retrive Fields checkbox and read the fields manually with the Read fields button. In this case all the fields will be of type String: This is the case of the JavaBean collections where the record concept is substituted by that of the java object.

In this case the fields are the object attributes.

By selecting the JavaBean Datasource tab, it is possible to register the fields which are read by a specified java object, in this case the object: By pressing the Read javabeans attributes button after having specified the name of the class to analyse, the attributes are extracted and presented as fields.

Later we will see the exact way this datasource is functioning, but in the JavaBean Ext Datasource tab there is a tool similar to that seen for the introspection of a JavaBean. This tool doesnt return a plain list of the available attributes for the explored JavaBean, but permits a more in depth exploration using a tree view where primitive attributes like the strings and numbers are represented by leaves, others are more complex types other bean that can be further exploded.

The way to reach a specific data in the Bean is stored in the field description with a syntax similar to that used for the java packages. In order to add a field to the list, it is necessary to select a tree node and press the Add field s button. Fields and textfield To print a field in a text element, it is necessary to set correctly the expression and the textfield type, and if it is necessary, to define a correct pattern for the field formatting.

It is possible to automate the setting of the expression and of the type by draging the field from the fields list into the desired report band drag n drop feature.

Parameters The parameters are values that usually are passed to the report from the program which creates the print and they can be used both to guide particular behaviours during the running phase such as the application of a condition in a SQL query , and to supply additional data to the print context such as an Image object containing a chart or a string with the report title. As with the fields, the parameters are also typed and they have to be declared at design time.

The parameters types can be arbitraries. At the moment the property is for prompting is not used by iReport and it is not relevant for the aim of the print: In an expression we refer to a parameter by using the syntax: Remember that the parameters as the variables are java objects, so it is not possible to use for the default value an expression like this 0. Use of parameters in a query As already said, a possible use of the parameters is to filter a SQL query.

Suppose you want to print information about a particular customer identified by their Id not known at design time. Our query will become something like: JasperReports will transform this query in: If you want to avoid this kind of parameters managing, it is possible to use the special syntax: Map interface.

Consider the code listed on the page 27, in particular the following lines: HashMap object.

To use in the report a parameter that contains for example the title of our report like it is shown in the figures 7. It is not mandatory to pass from the program a value for all the parameters declared in the report. If is not explicitly set a value for a parameter by the program, JasperReports will use the Default Value Expression to calculate the predefined value of the parameter; the empty expression is synonymous of null.

In reality the example is not very interesting because the data type passed is a simple string, however it is possible to pass to the report through the Map some Image or the instance of a datasource usable to feed a particular subreport. Moreover it is important to fill a parameter with an object having the same type of the declared type for the same parameter, otherwise a ClassCastException will be thrown. Built-in parameters JasperReports provides some built-in parameters they are internal to the reporting engine , which are readable, but not modifiable from the user.

These parameters are presented in table 7. Map passed to the fillReport method and it contains the parameters values defined by the users. It is the datasource used to create the report when it is not used a JDBC connection. It represents the scriptlet instance used during the creation; if no scriptlet has been specified, this parameter focuses on an instance of net. Variables The variables are objects used to store the results of calculations such as subtotals, sums, etc As the fields and the parameters, the variables are typed, that is its mandatory to declare the java type of which they are instances of the Variable Class Type.

See the meaning of each field. Variable name it is the name of the variable; in a similar way to what happens for fields and parameters, in the expressions we refer to a variable through the following syntax: String and java. Double; Calculation Type it indicates the type of a predefined calculation of which the result has to be stored by the variable; the predefined value is Nothing that means dont perform any calculation automatically; JasperReports perfoms the specified calculation changing the variables value for every new record that is read by the datasource: The calculation types are the following: Calculation types It does no kind of calculation type; it is used when the calculation is intrinsic into the expression that is specified from the user and that will be valuated to each new record.

Count It counts how many times the expression result is different from null; do not confuse it with sum that makes real sums based on the expression numerical value. Sum It adds to each iteration the expression value to the variable current value. Average It makes the arithmetic average of all the expressions received in input. Lowest It returns the value of the lowest expression received in input. Highest It returns the value of the highest expression received in input.

StandardDeviation It returns the standard deviation of all the expressions received in input. Variance It returns the variance of all the expressions received in input. System It makes no kind of calculation and the expression is not evaluated; in this case, the report engine keeps only in memory the last value set for this variable; it can be used to store the calculation result performed for example using a scriptlet. Table 7. Reset types The Initial Value Expression is always ignored The variable is initialised only once at the beginning of the report creation by using the Initial Value Expression Page The variable is initialised again in each new page Column The variable is initialised again in each new column or in each page if the report is composed by only one column Group The variable is initialised again in each new group the group we refer to is specified in Reset Group Table 7.

Custom Incrementer Factory Class it is the name of a java class that increases the JRIncrementerFactory interface, useful to define operations such as the sum for non-numerical types; Variable Expression it is the java expression that identifies the input value of the variable to each iteration; Initial Value Expression it is an expression of which evaluation produces the variable initial value.

Built-in variables As for the parameters, JasperReports puts at the user disposal some built-in variables that are directly managed by the reporting engine , they are readable, but not modifiable by the user. These variables are presented in table 7.

Tutorial iReports

At Report time this variable will contain the total number of pages It contains the current number of columns Current number of records that have been processed Current number of records that have been processed in the current page Current number of records that have been processed during the current column creation Current number of records that have been processed for the group specified as variable prefix.

In the chapter 4 we explained the report structure, and we have seen how the report is divided in bands, horizontal portions of page that are printed and modified in height according to the band properties and content. Here we will se how to use the groups, how to create some breaks in the report, how to manage subtotals etc Bands JasperReports divides a report in seven main bands and the background eight bands in total.

To these other two bands are added, the group footer and the group header. Through this window it is possible to modify the main properties of a band, its height, expressed in pixel Band Height , the possibility for the band to be break if it is overflow from the page Split allowed and the Print When Expression, that is an expression the must return a Boolean object and of which valuation determines the print.

In this case the empty expression represents implicitally the expression: Into the expression it is possible to use fields, variables and parameters, by paying attention to produce as a result a Boolean object.

Even if it is specified esplicitly, the band height can increase if one or more elements it contains grows vertically it can happen for textfield elements of which contents exceed the specified dimensions or for the subreports. JasperReports guarantees that the band height is never inferior to that specified. In order to resize a band it is possible to use the bands window figure 8.

A double click on the inferior margin allows to resize the band by adapt the height to the content. If one or more consecutive bands have zero height, it is possible to increase its dimension by keeping press the Shift button and to move towards the bottom the inferior margin in the band that precedes it.

By moving an element from a band to an other, the band to which the element is associated, is changed automatically. Groups The groups allow to group the records of a report in order to create some ruptures. A group is defined through an expression. JasperReports evaluates this expression: We will explain the use of the groups through an example created step by step. Suppose to have a list of people: Run iReport and open a new empty report. The first thing you have to think to is the order of record selection: JasperReports makes no order of records coming from a datasource; for this reason when you think about a print containing some groups, you have to order the records yourself in a right way.

We will use the SQL query: The result should be similar to that of the figure 8. A group is identified by several properties: Group Name it specifies the group name; the name will be used to name the two bands associate to the group: Our expression has to return the first letter of the name; an expression like this We have to test these two conditions with an expression like this: Added the new group, in the design window two new bands appear: InitialHeader and InitialFooter.

Insert in the InitialHeader band a textfield with the expression used for the group figure 8. Here the final result figure 8. The number of possible groups contained into a report is arbitrary, a group can be contained in a parent group and contain other children groups. The result is a groups list. It is possible to change the priority of a group respect to another group through the Move Up and Move Down buttons present in the groups list frame fig. To change the priority of a group means also to change the position of the bands composing it.

More is the priority, more the group bands are far from the detail band. The subreports represent one of the most advanced functionalities of JasperReports and they make possible the realization of very complex prints. The aim is to be able to insert a report into another report created with modalities similar to the first one. We have seen that to create a print we need three things: In this chapter we will explain how to pass these three objects to the subreport through the parent report and by creating dynamic connections that are able to filter the records of the subreport on the grounds of the parents data.

Then we will explain what tricks can be adopted to give back to the parent report information regarding the subreport creation. Create a subreport As we have already said, a subreport is a real report composed of its own XML source and compiled in a jasper file. To create a subreport means to create a normal report. You have to pay attention only to the print margins that usually are set to zero for the subreports. The horizontal dimension of the report should be as large as the element where it will take place into the parent one.

It is not necessary that the subreport element be exactly as large as the subreport, however in order to avoid unexpected results, it is always better to be precise. In the parent report it is possible to insert a subreport using the subreport tool; what is created is an element similar to the rectangle. The subreport element dimensions are not really meaningful because the subreport will occupy all the necessary space without begin cut or cropped. We can think as if the subreport element only defines the position of the top left corner to which align the subreport.

Link of a subreport to the parent report To link the subreport to the parent one means to define three things: All this information is defined through the subreport properties figure 9.

The properties are divided into two tabs: Subreport and Subreport Other. The Parameter Map Expression is probably the method least used to set the values of the subreport parameters, but is the first property of the subreport element encountered in the properties window; it allows you to define an expression of which result has to be a java.

Map object. If you leave this field blank, a void map will be passed to the subreport this is not true if we define some subreport parameter values as well see soon. The limitation of this mechanism is the immutability of the parameters passed in the map. You can see the Subreport parameter table in figure 9. Also in this case the interface is quite selfexplanatory: The parameter name has to be the same as the one declared in the subreport. The names are case sensitive, that means capital and small letters make the difference.

If you make an error typing the name, or if the inserted parameter has not been defined, no error is thrown but probably you would ask why something is not working The expression is a classic JasperReports expression where it is possible to use fields, parameters and variables. The return type has to be congruous to the parameter type declared in the subreport, otherwise there is an exception of ClassCastException at runtime.

One of the most common uses of the subreport parameters is to pass the key of a record printed in the parent report in order to execute a query in the subreport with which you can extract the referred records report headers and lines. To specify the datasource To set the subreport datasource means to tell JasperReports how to retrieve data to fill the subreport. There are two big datasource groups: JDBC connections and Datasource.

Using JDBC to fill the report makes the use of the subreport simple enough. In this case the Connection Expression defines a java. Connection object that is already linked to the database.

File:Adempiere Ireport Integration Manual 1.1.pdf

By using a Connection Expression, it is a foregone conclusion that the report will be created starting from the SQL query contained in the subreport. The use of a datasource is more complex: However the use of an expression allows some kind of freedom for the production of the datasource. A datasource is in general a consumable object that is usable for feeding a report only once; so a datasource passed as a parameter will satisfy the needs of only one subreport.

So therefore the parameter technique is not suitable when every record of When we explain the Datasource we will see how this problem is easily solvable by using custom datasources. To specify the subreport To specify what.

iReport NB 3 Tutorials

The type of object returned from this expression has to be selected from the combo box that precedes the expression field see figure 9. The possible types and their semantic meaning are listed in table 9.

Possible return types of the Subreport Expression It represents the jasper file preloaded in a JasperReport object java.

InputStream It is an open stream of the jasper file java. File It is a file object that identifies the jasper file java. String It identifies the name of the jasper file Table 9. If the expression is a string, it uses the JRLoader class to load the file starting from the specified location, in particular the string is at first interpreted as URL, in case of MalformedURLException the string is interpreted as a physical path to a file: This means that if you refer to a file, the string has to contain the absolute path where it is, or you have to put your jasper files in the classpath and refer to it using a java resource path.

A step by step example Lets put into practice what we saw in the previous paragraph. We want to print an orders list with each orders detail rows.

Open an empty report. Select the report: Press OK button: Drag the three fields into the detail, save the report with a name as you like for example master. The query of this subreport will use this parameter and it will be: In order to correctly read the query fields, it is necessary to associate a default value for the parameter for example the empty string.

Save the subreport for example with the name customers. The vertical dimension of this element is not important because during the print creation JasperReports will use all the necessary vertical space 9.

Set the subreport properties by opening the element properties window and move in the Subreport tab. In the Subreport Other tab specify where to find the customer. As expression for the subreport, simply specify the jasper file name to use as subreport. By using iReport, we are sure that the subreport will be found by specifying only its name without an absolute path because the directory where the subreport is stored, will be automatically added to the CLASSPATH and so In other cases it could be necessary to specify the directory path where there is the subreport as parameter and to specify an expression like this: To do that, add a new line in the parameters table of the subreport by specifying the parameter name of the subreport and its expression that creates the value to give to the parameter.

Compile master. If everything is ok, you should obtain something like that in the figure 9. Proceed with the second subreport to view the detail of the order. Once again start from an empty report, remove the margins, define the parameter linked to the master; in this case the ORDERID parameter declared as java. Integer, and insert the query for the selection of the order detail rows: Set the height of the not used bands to zero all except for the detail and insert in the detail band the fields we want print fig.

The file will be details. You have just to compile again the master and run the final print. The final result should be something like that in the figure 9. Return parameters JasperReports dont provide an explicit mechanism to return parameters from a subreport to the parent at the end of the subreport filling process. However this functionality could be useful in many situations, for example when you want to print in the parent the total number of records processed in the subreport, or to return the result of a particular elaboration executed in the subreport.

It is necessary to think about a trick to avoid both these problems. In reality, the solution is simpler than what you might think: HashMap parameter to share a memory location between the parent and the subreport. Passing this parameter to the subreport, we will fill the HashMap by putting values we want to give back with predefined map keys.

In this way we do not give a new value to the parameter that is not possible , but we will modify the content of the HashMap, which can be done. You now have to find a way to execute an instruction like this: This expression does not produce values. So you have to use an external class that expose a method able to produce the same result of the expression and that returns an arbitrary value. The code of a simple class that can do what we need is the follow: HashMap map.

The class is simple: To use the proposed method and obtain the desired result, we can add to the report for example in the summary a dummy element i. Do not worry too much about the element type because this will be never printed because addMapValue always returns the boolean value false. Choosing the right position of the hidden element into the report allows us to choose when and how many times the addMapValue must be executed. There are two types of datasources: The ability to retrieve the data to print from a relational database through a SQL query makes the reports creation extremely simple, because it is possible with a mouse click to register the query fields as report fields without having to specify the name and the type of each single field.

When it is not possible to access data through JDBC or when you do not want JasperReports to interacts directly with the database , it is necessary to use a JRDataSource that means JasperReports Data Source , which is an interface that allows access to data as if they are structured in tables and organized in lines and columns the lines are named records of the datasource and the columns are the record fields. The program will pass to the fillReport method of JasperReports an opened connection to a database a java.

Connection object or the instance of a JRDataSource due to fill the report. In the first case, JasperReports will use the supplied JDBC connection to execute the SQL query specified in the report obviously this query is defined only if you want to print the report by using this method. The result of the query typically a java. In this way JasperReports associates the data to print with a JRDataSource object, which represents the generic interface used by this library for managing the data to print.

In this chapter, we try to clarify the different types of JRDataSource that are at our disposal and how they can be used in iReport. Main report page consisting of a set of tabs. Each tab port is outlined below using an example iReport cre- consisting of one or more content items.
