This tutorial is a pretty common one we run all the time. Problem adding a
module to the server sounds like there could be one of a couple things. I
will give a blurb of things to try and check around to see what the error
1. Could be the dynamic webproject, make sure its runtime is targeted to
2. Make sure on that page apache is chosen.
3. Make sure your tomcat install is ok
or this could be a new bug i will check further but this tutorial was
working not to long ago so maybe you missed a step along the way.
