Following up on my deployment troubles with webservices, I found the final reason to be, that ws4ee is not installed with the ejb3-profille of the jboss4.0.3-installer.
As we have already started to change the server (added new Classes, changed configurations etc.), is there a possibility to deploy the ws4ee afterwards?! I didn't find any separate distributions for ws4ee. Can I simply deploy the ws4ee.sar that comes with jboss4.0.3 in an existing jboss-installation? Anything else I need to copy/deploy?!
There is no possibility to install missing/uninstall unneeded Features via the graphical installer, or did I only miss that option?!
As the ejb3 profiler expands to include the javaee 5 webservices, ws4ee it will be included in it.
