Employment/Purpose

The JasperReport component. It is used to generate a Jasper report into an inline frame

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("/userguide/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
