Hi, I'm new to Jasper Report and currently supporting the already live reports on production for any enhancement / issues. I need to paas multiple parameters to Jasper Reports. And don't know the syntax for same. The below link is used to call a folder "Employment_Application" on server and pass a value of 100 to "id" parameter of each JRML file exists in that folder. http://myserver.domain.com:8080/PDFReport/asdf.pdfreq?formtype=Employment_Application&id=100 Queries: 1) Though from above link its clear visible that we are passing a value of 100 to a parameter "id" but I checked the jrxml report and did not able to find this parameter defined anywhere. Instead there is a parameter name "REPORT_APPLICANT_ID" defined and getting this value 100 from this link and working perfectly. How is this "id=100" is linked to "REPORT_APPLICANT_ID" ? "REPORT_APPLICANT_ID" has isForPrompting="true" property set. 2) I now have created one more parameter in report named "SUBREPORT_DIR" and need to pass a value to it at run time. "SUBREPORT_DIR" has isForPrompting="false" property set and has been assigned a default value in report. How can I pass the value to this parameter from above link along with current parameter ? Please help me....
