j2ee development environment?

I'm starting a j2ee project and I was trying to see if it's beneficial (and how to) setup a local j2ee server to test on, much like the .net development server runs. I have a development spot in our enterprise development server, which is where I'll do most of my testing, but I was just curious if there was any benefit to having a local running copy for debugging or other such uses. Thanks!

• Oh yes, local dev environment is way to go. Especially with eclipse, since it can hot deploy your code.

  toolkit : Yep. Definitely. Use your own Java EE appserver.

  Tim Williscroft : Use Netbeans, and you can profile your local appserver. Profiling could work in eclipse but TPTP is very hard to get to work.

  lock : oh just to add, whether local or not, for debugging - log4j is indispensable :)
