Problem: Java heap space

[jiurriza]

I'm generating a report in pdf format with over 20.000 pages (1 page per item in the database with all the information of that item), and when I try to view de report I get a java.lang.OutOfMemoryError, Java heap space error.

 

I'm using Eclipse, iReport and JasperReport. When I run the report to preview it on iReport everything goes well...the problem is when I run it from my web application.

 

Does anybody have any clue on how I can solve this? Any help is appreciated.

 

Thanks

 

Cheers,

Jose I.

In JVM settings from Eclipse set:

-Xmx512m (or -Xmx1024m)

-XX:MaxPermSize=256m

 

and see if you get the same error.

Thanks for your reply...Unfortunately it didn't work.

 

Just to be sure I did it the right way, I went to eclipse preferences -> tomcat -> jvm settings -> and I added both -Xmx512m and -XX:MaxPermSize=256m to the "Append to JVM parameters". I also tryed with 1024m.

 

Anything else I could try?

On my machine i have also -XX:NewSize=200m. If this one doesnt help either, i'm out of ideas.
