Birt Report generated without data for 2nd time

deekay

Hi, 
 
I'm using the below code logic to generate the BIRT report in PDF from Servlet. 
<a class='bbc_url' href='http://wiki.eclipse.org/Java_-_Dynamic_Report_Servlet_(BIRT)'>http://wiki.eclipse.org/Java_-_Dynamic_Report_Servlet_(BIRT)</a> 
 
When i generate the BIRT report for first time it successfully generates. I'm unable to generate the BIRT report if is call BirtEngine.destroyBirtEngine() method in doPost() method at the end. This generates the report only one time. Can anyone help me to get rid of this issue? 
 
Thanks, 
Deekay

Deekay,

Why are you destroying the engine? You should only do that if the application is shutting down.

when i generate the 70 -80 reports it starts giving me below Exception : 
 
java.lang.OutOfMemoryError: PermGen space 
 
So to release the memory i was destroying the report engine. 
 
Can you please suggest any solution to get rid of this issue? 
 
i'm using these JVM parameters (-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled)
