Subject Re: Cocoon is complex, HOLD ON, WHY IS THIS BOILING UP ?
Date Sun, 26 Jan 2003 03:18:38 GMT
The biggest concept that has me is. "Ok so this is cocoon including everything
but the kitchen sink... so where do I start on my OWN site? Do I need to copy
this enormous cocoon config file? Haven't they ever heard of defaults? Do I
really need to hand modify all his stuff? Why is everyone telling me to build
the blasted thing from source? Cocoon.xconf ? Do I need this in my new war? Holy
Christ there are allot of jars (28 is still allot .. prepack them in the
distrib). Logikit? I use log4j for everything else. After all its the best
logging package ever made! What's with logikit?"

Those are the things that pop to mind.

Other things vary such as "why the heck wont JBoss let me redeploy this sucker?"
One question I got when I undeployed it from JBoss and dropped it back in and
then hit the URL and watched IE wave its flag at me for 5 min in some sort of
endless loop.
