The problem is that there is only a partial deployment descriptor in the tutorial that does not mention where I should put the service tag. Unfortunately I couldn't even find any references to the deployment descriptor XSD or DTD, so I couldn't figure out myself. The tutorials that i pointed to also have the downloadable source code. Here's the jboss.xml with the xsd declaration http://anonsvn.jboss.org/repos/jbossas/projects/ejb3/trunk/docs/tutorial/... anonymous wrote : | I finally found the DTD of jboss.xml (jboss_5_0.dtd under docs/dtd).

For EJB3 on JBoss, the DTD for jboss.xml cannot be used. You will have to the xsd as shown in the above SVN file.
