Allan,
I can't help but I can share the pain.

I'm currently going thru the same learning curve deploying applications in WebSphere. I view the huge learning curve as a J2EE issue, and not a WebSphere specific issue. Does it really have to be this complicated to deploy a frickin application.
Anyway, good luck to both of us.
Mike
By the way, FWIW, James posted a link a couple of threads back on what looks to be a good WebSphere 4.0 tutorial.
http://www.webspherepro.com/wparchive/was4tutorial/was4Tutorial.html I will be going thru it in the next couple of days, and will give you some feedback.
