This question touches a few ways to create reports using the JasperReports API (either directly or indirectly): iReport JasperReports API DynamicJasper DynamicReports DynamicReports (DR) and DynamicJasper (DJ) are two free and open-source software tools that abstract (and simplify) common tasks with the JasperReports API. If you are considering developing reports programmatically, these tools can cut … Read more
Set the property isBlankWhenNull to true. In iReport check the Blank When Null checkbox when your field is selected. In jasper jrxml file: <textField isBlankWhenNull=”true”>
Parameters are simple input to JasperReports. You have to define parameters in the JasperReport before using them. You can display the value of the variable, you can use it as part of boolean expressions and you can even pass it to subreports. This can be an input to SQL query. Fields are simple variable definitions. … Read more
It is quite easy to solve your task. You should create and use a new variable for summing values of the “Doctor Payment” column. In your case the variable can be declared like this: <variable name=”total” class=”java.lang.Integer” calculation=”Sum”> <variableExpression><![CDATA[$F{payment}]]></variableExpression> </variable> the Calculation type is Sum; the Reset type is Report; the Variable expression is $F{payment}, … Read more
In iReport set Ignore pagination to true in your main report’s properties. This should cause your footer to be render at the bottom of the content in your details band.
The locale is set during execution, not in the JRXML. Using Java, set the REPORT_LOCALE parameter for the report’s parameter map. For example: InputStream reportTemplate = getReportTemplate(); JRDataSource dataSource = getDataSource(); java.util.Map parameters = getParameters(); java.util.Locale locale = new Locale( “en”, “US” ); parameters.put( JRParameter.REPORT_LOCALE, locale ); JasperFillManager.fillReport( reportTemplate, parameters, dataSource ); Using Jaspersoft Studio, … Read more
You can pass datasource via the built-in REPORT_DATA_SOURCE parameter. The example: <subreport> <reportElement x=”261″ y=”25″ width=”200″ height=”100″/> <dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></dataSourceExpression> <subreportExpression><![CDATA[$P{SUBREPORT_DIR} + “subreport.jasper”]]></subreportExpression> </subreport> You can create new instance of datasource based on variable, parameter or field. The sample: <variable name=”HeadingsCollection” class=”java.util.Collection” calculation=”System”> <initialValueExpression><![CDATA[new java.util.ArrayList()]]></initialValueExpression> </variable> … <subreport> <reportElement x=”0″ y=”0″ width=”515″ height=”20″/> <subreportParameter name=”ReportTitle”> <subreportParameterExpression><![CDATA[$P{ReportTitle}]]></subreportParameterExpression> </subreportParameter> … Read more
It is possible to use execute multiple queries from a single report by using a subDataset and datasetRun. The behaviour is like having one or more subreports embedded into a single report file. Define a subDataset like this: <subDataset name=”dataset1″> <parameter name=”someParam” class=”java.lang.String”/> <queryString><![CDATA[SELECT column1, column2 FROM table1 WHERE column1=$P!{someParam}]]></queryString> <field name=”column1″ class=”java.lang.String”/> <field name=”column2″ … Read more
