Employment/Purpose

The JasperReport component is based on a 3rd party JasperReports Library, a report generator (e.g. XML generator, PDF generator etc.). This component is used to generate a Jasper report into an inline frame.

Including Dependency

Since 9.6.0 ZK doesn't include jasperreports by default. If you need to use this component, you have to include the dependency manually like:

<dependency>
	<groupId>net.sf.jasperreports</groupId>
	<artifactId>jasperreports</artifactId>
	<version>6.17.0</version>
</dependency>

3rd Party Vulnerability Notice

Jasperreport uses another external library called itext 2, and there are some vulnerabilities reported on org.bouncycastle:bcprov-jdk15on, which is a dependency of itext 2. If you are concerned, you can exclude that dependency, it does not affect the use or the PDF exporting of this component. Alternatively, Jasperreport does provide a separate PDF Exporter with a newer version of itext which does not contain the affected bouncycastle lib. For more information, please check JasperReports PDF Exporter Lib Seven.

Example

	<jasperreport id="report" height="360px" />
	
	<zscript>
		import org.zkoss.zkdemo.userguide.CustomDataSource;
		
			//Preparing parameters
			Map parameters = new HashMap();
			parameters.put("ReportTitle", "Address Report");
			parameters.put("DataFile", "CustomDataSource from java");
			
			report.setSrc("/data/jasperreport.jasper");
			report.setParameters(parameters);
			report.setDatasource(new CustomDataSource());
			report.setType("pdf");
	</zscript>

Provide Export Parameters

The Jasperreport component API provides a way to specify export parameters. To do so, you should put a Map containing export parameters within the parameters Map, with key "exportParameter". For example:

	Map parameters = new HashMap();
	Map exportParams = new HashMap();
	exportParams.put("net.sf.jasperreports.export.mypropertyname", true);
	parameters.put("exportParameter", exportParams);
	report.setParameters(parameters); // report is the Jasperreport component

One-Page-Per-Sheet Property

In Jasperreport engine, this property is default to be false. However, the default behavior is turned on in the Jasperreport component, in which case when the report is exported as Excel format there will be one sheet generated for each page. To override this setting, set it as an export parameter as the following:

	Map parameters = new HashMap();
	Map exportParams = new HashMap();
	exportParams.put(JRXlsAbstractExporterParameter.PROPERTY_ONE_PAGE_PER_SHEET.toString(), false);
	parameters.put("exportParameter", exportParams);
	report.setParameters(parameters); // report is the Jasperreport component

exportName

Since 8.6.1

You can specify the export file name for the download if any, the full file name will be exportName + "." + format.

Note: exportName can not be empty or null.

Default: "report"

<jasperreport exportName="test"/>
