java.lang.OutOfMemoryError: PermGen space comes up.

hi:
thanks for replying
the app is running on a powerful server and the memory is suppose to be
enough
I'll check if there is a memory leak,(althouth the app is suppose to use

hi:
I've wrote an app with jsp and servlet, and I used four libs
commons.logging
common.httpclient
jdom
commons.codec
the app works pretty well on my pc, and the tomcat is apache-tomcat-6.0.29
however , when I put this app on to another computer with the same tomcat
it throws this exception
Java
hi:
thanks, the problem is that my tomcat interact with other server and the
server use somekind of encoding that is different.
and after the encoding is transfered .it works now
thanks
