Out of Memory Errors

2004-04-02 09:21

My first Jasper report looked beautiful when run on a dataset containing 1000 or so records but when I hit it with a dataset of 100000+ it started pegging my CPU at 100% for a considerable time, finally dying with an OutOfMemoryException.

 

In looking at the docs, it seems there is a subReport tag that might be of use to me to in solving this problem.

Can someone tell me if that is the case before I run down this path? Or is there another way to handle it?

Well, with so much data, subreports might not help much. Try increasing your jvm's memory allocation first.
