     System.gc();
  HttpSession session = request.getSession(false);
  Object reportSource = getReportSource(request, reportPath);
  ReportExportControl exportControl = new ReportExportControl();
  if(paramList != null && paramList.size()>0){
   exportControl.setParameterFields(getParamFields(paramList));
  ExportOptions exportOptions = new ExportOptions();

Hi,
I have tried this code but stil the same.
However i tried setup another tomcat and application in the other machine and the only job for  the application is exporting the report that has problem, then the error is gone.
So i guess that is the memory size problem.
Thanks for this
One more question about the memory size between Tomcat and Crystal report.
I have set in catalina.bat as
set JAVA_OPTS = "-Xms2048M -Xmx1024M"
and CRConfig as
<JVMMaxHeap>1024000000</JVMMaxHeap>
<JVMMinHeap>512000000</JVMMinHeap>
1. Is that the correct setting.?
2. The memory in the JAVA_OPT and is the MAX and MIN memory that java would use,
    then is the Max memory in CRConf is 1024M out of the java heap size or the application use another 1024 memory
