Jasper report parameters

[kevinjia1984]

Hi all,

I'm new to jasper report and I'm using ireport 4.0.1 for jrxml design. Just want to ask if I put some new values in the parameter map when calling JasperFillManager.fillReport, Do I have to create some new parameters in ireport regarding the keys I set in the parameter map when calling JasperFillManager.fillReport or all the new parameters will be inside "REPORT_PARAMETER_MAP"? For example:

Map parameters = new HashMap();

parameters.put("value1", value1);

parameters.put("value2",value2);

JasperPrint jasperPrint = JasperFillManager.fillReport(myProgramStream, parameters, jasperReportDS);

So in ireport, the value1 and value2 have already been in REPORT_PARAMETER_MAP or I have to create two new parameters named "value1" and "value2" in the related jrxml?

Many thanks for any help.

You must define params "value1" and "value2" in jrxml

Thanks sanbez.And could you tell me what's inside the REPORT_PARAMETER_MAP?

[sanbez]

This map contain values of parameters for report execution. See http://community.jaspersoft.com/system/files/documentation/jasperreports-ultimate-guide-3.pdf
