How to use xml data source on jasper server

[maciejwenerski]

Hi, I would like to use xml data source in jasper server (5.0.0). Xml files are created "on the fly" while application is running so different reports will have different xml data sources. I know that jasper server does not have XML data source defined but I found out that creating report without data source and then passing parameter XML_FILE - java.io.File will do the work. I managed to do this in java servlet: 

      jasperReport = JasperCompileManager.compileReport("C://FileIO//XMLDSReport.jrxml");       

      HashMap map  = new HashMap();

      map.put("XML_FILE", new File(xmlSourceFile));     

      jasperPrint = JasperFillManager.fillReport(jasperReport,map);        

    byte [] o = JasperExportManager.exportReportToPdf(jasperPrint);

 

but unfortunately failed to do it on jasper server. I've tried to write a scriptlet that converts String parameter with xml url to java.io.File 

 

    public class XmlScriplet extends JRDefaultScriptlet{

   @Override

public void beforeReportInit(){

try {

String param = (String)this.getParameterValue("fileName");

HashMap map  = new HashMap();

map.put("XML_FILE", new File(param));

this.parametersMap.putAll(map);

 

 

} ...

 

but this gives me an empty report. 

Thank you in advance.
