java.lang.OutOfMemoryError

2003-12-17 09:31

I have a report(CRP) with subreport(crp-subreport).

THe main report contains static as well as some dynamic data and is page full. The main report calls the subreport.

File: D:iReport-0.1.0integrationTestCRPCRP11.xml

Compiling to file... D:iReport-0.1.0integrationTestCRPjasperCRP11.jasper

Compilation running time : 2469

Opening connection....

 

java.lang.OutOfMemoryError

 

<<no stack trace available>>

 

Abnormal termination!

 

If i remove some portion of the main report then it works fine.

 

Did any one come across such problem if so please let me know .

 

Thanks

Pandu

Hello. I am having similar issue with Jasper Report Server - java.lang.OutOfMemoryError: Java heap space, on upgrading to Jasper Report 6.5.1.This is making the application completely unresponsive.

The issue occurs at multiple locations and logs provided below. I have set the JVM Heap space to 8GB, but still does not help. Please let me know if you have any solutions. Thanks in advance.
