Testing Server side code

Has anybody worked with JunitEE or Cactus (both extensions of JUnit, a unit testing framework) to test Servlets, JSPs and EJBs. If yes, do you have any opinion on which is a better framework to use for testing. Did you come across any specific issues using these tools.
Thanks for your time..

Raj,
I hate to suggest you look outside of JavaRanch

But a few months ago after the XP Universe conference (where I led a workshop on J2EE Testing) we set up a mailing list for J2EE testing issues.
See here:
http://groups.yahoo.com/group/xptesting

The reason I suggest this is that I know several of the participants have tried the tools you mention.
