How to increase java memory space

Question

I encounter java out of memory: perm gen exception. I tried to resolve it by expanding the java heap size, but unable to solve it. How can I increase the memory?

is it for standalone java app or a webapp in a web container? — Juned Ahsan, Nov 04 '13 at 16:36

You need to use a directive like this when starting Java: -XX:MaxPermSize=128m

PermGen is where class definitions and such are stored. It's not part of the same body of memory that is referenced by things like Xmx and Xms.
