My application based on several jar files: login.jar, mainform.jar, reportview.jar.
The login jar calls mainform.jar and it'll call report view.jar likewise.
So in reportview class i have a method for showing report with JasperViewer:
reportSource = Reportpath + getReportname() + ".jasper";
HashMap para = new HashMap();
para.put(getReport_param1(), getParam1());
para.put(getReport_param2(), getParam2());
para.put(getReport_param3(), getParam3());
para.put(getReport_param4(), getParam4());
para.put(getReport_param5(), getParam5());
JasperPrint jp = JasperFillManager.fillReport(reportSource, para, con);
JasperViewer.viewReport(jp, false);
So as single project its run 100% correctly and view report.
But when i'm import this class to mainform and call reportview method it didn't run. I used
jasperreports-3.1.4.jar file for JasperReports library. It work fine when calls report module by its main methos.
But when calling from different jar it gives this error.

Please help me to solve this problem.
