Java allocates 64MB of memory per process by default. If you're getting an OutOfMemory error, then you're exceeding it.

Check the documentation for Tomcat4 (which I think is what you're running), and see how you can boost the max allowed memory.

Another possibility is that you have some sort of recursion or infinite loop that keeps allocating objects until the JVM finally runs out of memory. I'd suggest taking a close look at your code. If you can't find the leak, you might try running it through a debugger or profiler.
