Thanx for your detailed reply.
What I did was to add the following fragment of code in the
JasperReportResult.java of the jasperReport-plugin
.
.
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(systemId);
/**
* Edited
*/
JRParameter []reportParameters = jasperReport.getParameters();
for(int i=0; i<reportParameters.length; i++){
if(!reportParameters[i].isSystemDefined()){
parameters.put(reportParameters[i].getName(),
stack.findValue(reportParameters[i].getName()));
}
}
.
.
It checks whether there are non System defined parameters. If parameters
exist it assigns values from the value stack. Thus, I have to set the
parameters in the action and set names that are the same with the report
parameters (e.g. I had a jasper parameter named referenceNumber and a
setter/getter in my action for the referenceNumber variable)
