Hello All -- I've been to the Tomcat forums already originally
thinking it was a servlet container issue. I don't think this is the
case anymore.
I have made a simple generic gwt rpc module.. When I run in hosted
mode, everything is great. When I deploy my WAR file, the client side
stuff works, but no servlet. Does anything jump out?? I've been
fighting this for a couple of days.. I keep coming back to the
conclusion that my container is configured wrong.
A bit more info about container.. I'm running Ubuntu 8.10 / Apache2 /
tomcat6 / mod-proxy
Apache and Tomcat appear fully functional.. I have also successfully
added a proxy to take me to port 8080 when calling my webapp. I've
posted similar data to TomCat forum, and judging from responses, I
have the container properly configured?
I've also tried re-arranging my WEB-INF/ structure...
It was original WEB-INF/classes/MsgServiceImpl.class
not it is WEB-INF/classes/com/i2s/webMonster/server/
MsgServiceImpl.class
I don't think I have a clue at this point...
Thanks in Advance, Attached below are my code/logs
