Try setting the Maximum size property of the jvm while starting jvm

-XX:MaxPermSize=128M

You can read more about the option here, here and here

My shared server heap size is 64Mb. There i am not getting option for heap size setting – user2302288 May 13 '13 at 08:26
@user2302288 it is not a heap problem, Perm space is a different space. which is the container used and how is it started – Arun P Johny May 13 '13 at 08:30

Yes definitely it's not a heap problem.

Permgen space problem occurs if there is any error while loading a class. So, here your class is not loaded properly meaning you have a less permgen ( different from heap size and is also configurable attribute in jvm ).

How to detect which class in not loading properly – user2302288 May 18 '13 at 04:22
I have no idea about this but the classloading problem is solely due to the fact that there isn't any free space to load your class definition in memory. Rather , I would advice to first try increasing the Permgen size and then to see the consequence. – Shailesh Pratapwar May 18 '13 at 11:34
