This file cannot be found. However if I keep any pdf / adobe open it is able to open the pdf for mulitple request (submits ) if I close the pdf it is able to generate the pdf only for the first time and not the second time. Please help me resolve the issue, its urgent. thanx in advance Madhusudan HP

I am new to iReport and JasperReport. Please help me in resolving the no classdef error I created jrxml and compiled it to get a .jasper file using iReport. Then I use this piece of code pasted below to see a pdf open in my browser I am deploying it on WeblogicServer 9.2 I copied jasperreports-2.0.4.jar that comes with ireport into the lib of weblogic I am using JavaPageFlows. HttpServletResponse response = getResponse(); System.out.println(" response " + response.toString() ); InputStream reportStream = null; File jf = new File("productepc.jasper"); InputStream fileStream = new FileInputStream(jf); if( fileStream != null){ System.out.println(" fileStream obtained " ); } ServletOutputStream servletOutputStream = response.getOutputStream(); JasperFillManager.fillReport(fileStream,new HashMap()connection); JasperRunManager.runReportToPdfStream(fileStream, servletOutputStream, new HashMap (),connection); response.setContentType("application/pdf"); connection.close(); servletOutputStream.flush(); servletOutputStream.close(); =================================================== The error stack trace : java.lang.NoClassDefFoundError at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:147) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:57) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:402) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:363) at pageflows.jasperReport.JasperReportController.begin(JasperReportController.java:93) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.beehive.netui.pageflow.FlowController.invokeActionMethod(FlowController.java:878) at org.apache.beehive.netui.pageflow.FlowController.getActionMethodForward(FlowController.java:808) at org.apache.beehive.netui.pageflow.FlowController.internalExecute(FlowController.java:477) at org.apache.beehive.netui.pageflow.PageFlowController.internalExecute(PageFlowController.java:305) at org.apache.beehive.netui.pageflow.FlowController.execute(FlowController.java:335) at org.apache.beehive.netui.pageflow.internal.FlowControllerAction.execute(FlowControllerAction.java: 51) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:419) at org.apache.beehive.netui.pageflow.PageFlowRequestProcessor.access$201(PageFlowRequestProcessor.java: 95) at org.apache.beehive.netui.pageflow.PageFlowRequestProcessor$ActionRunner.execute(PageFlowRequestProce ssor.java:2042) at org.apache.beehive.netui.pageflow.interceptor.action.internal.ActionInterceptors.wrapAction(ActionIn terceptors.java:90) at org.apache.beehive.netui.pageflow.PageFlowRequestProcessor.processActionPerform(PageFlowRequestProce ssor.java:2114) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:224) at org.apache.beehive.netui.pageflow.PageFlowRequestProcessor.processInternal(PageFlowRequestProcessor. java:554) at org.apache.beehive.netui.pageflow.PageFlowRequestProcessor.process(PageFlowRequestProcessor.java: 851) at org.apache.beehive.netui.pageflow.AutoRegisterActionServlet.process(AutoRegisterActionServlet.java: 630) at org.apache.beehive.netui.pageflow.PageFlowActionServlet.process(PageFlowActionServlet.java:157) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:743) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:283) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java :3228) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2002) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:1908) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1362) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:181) Any help on this is much appreciated.
