Hello
You have this message:
Adding servlet
ServletModel{id=ServletModel-239,name='helloboard',urlPatterns=[/],servletClass=class
com..gcs.console.helloboard.HelloboardServlet,contexts=null}
With this, you're overriding the "default" servlet normally mapped to "/"
with your "helloboard" servlet mapped to "/".
I'll check in Servlets specification how this should behave, but for now
this looks like this is the reason. If you don't add this servlet, named
dispatcher should work.
regards
