Exception in ReplyHeaderFilter.doFilter on JBoss with MyFace

[demoncleaner]

Hi everybody,

I have a J2EE/MyFaces project running on JBoss 4.0.3 SP1.
Everything worked fine until my data structures became bigger and more complex. Now always after a short time of working I get this exception, no matter what kind of actions I perform. I'm new to web development and Java, and I don't have any idea how I could debug an error like this.

Has anyone experienced this before? Any help appreciated!

Greetings,
DC

This time I got a little more info.
Is there maybe any way I can increase the Java heap space??
