My application using axis2.I increased the heap size 1024mb.But its not working.What would be the problem.Solution please

Answer 1

PermGen and heap size are different from each other.

You need to increase permgen space like this:

-XX:PermSize=256m 
-XX:MaxPermSize=256m

add this flags.

Also look at this: explaining-java-lang-outofmemoryerror-permgen-space and this: how-to-deal-with-java-lang-outofmemoryerror-permgen-space-error

Hope this helps.
