important tip for installing struts within resin!

[Felix von Delius <fv...@t-online.de>]

Now I found a reason for my trouble: I had a copy of struts.jar in $RESIN_HOME/lib instead of having it only in my application's WEB-INF/lib. This caused resin not to find any application classes. After deleting struts.jar from $RESIN_HOME/lib everything works fine.

It costs me half a day to find out, so I hope this hint prevents some of you from wasting your time!
