Thank you, giving this hint solved my problem. The ejb itself was properly deployed (I had a common.jar file that had the two interfaces and serverside ejb file which had the ejb class as jar, and another ear file that contained both jar files as modules). However, I thought that I would also have to put the common.jar into the lib/ dir of the servlet.war file which was not the case.
