Java EE (Java Enterprise Edition) General Discussion

As a newbie to J2EE, I have been searching for an answer on whether dom4j could fit well within Sun App Server PE8 (SASPE8) but there isn't too much information around.

Can we use dom4j as in j2se? I am trying to port my application from j2se to j2ee but the road has been bumpy to me. I tried to read and parse XML contents from a jndi url, but the parsing wasn't successful.
