Virtualizer and Batch Export

[rajil]

Hi. I am facing some problem while creating JasperPrint objects using Virtualizer.

 

Actually, i have total 5000 reports to generate. each having 2 pages. (5000*2 = 10000 Pages).

I am using Batch Export to generate report in a single file.

To do this i am saving all 5000 JasperPrint objects into an Array List and Export them to a single file.

 

I am running this under Windows XP, Tomcat4.1, JDK 1.4, Jasper 3.0.

 

Now, it consumes lots of memory. Arround 600 MB of HeapSize.

 

I tried using all 3 Virtualizer, but it goes out of memory after processing only 2700 JasperPrint Objects even after setting HeapSize to 1.6 GB.

But without using Virtualize its working fine.

 

Also, I tried in both ways, using seperate Virtualizer Object for all JasperPrints (MaxSize=1) as well as using the same Virtualizer Object for all JasperPrints Objects (MaxSize=5001).

 

But in both cases it goes out of memory.

 

Can you suggest the solution.
