Hi,

I'm getting the PermGen exception from our web service. Just want to check other than analyzing through memory tools, are there any known bad practices which may cause PermGen memory leak? Thanks

The code of the sevlet

I've bumped up the memory size but the issue still exists.
"-XX:MaxPermSize=160m",
