I so much appreciate that you try to help me again!
I attached server.log.
First deployment happens after the unpacking the ear. The ear look like this:
ear
+-lib
+-...
+-META-INF
+-...
+-openempi-ejb-2.0.5.jar
+-openempi-webapp-web-2.0.5.war
I guess the deployer find the ejb jar file:
2010-09-10 11:03:31,877 DEBUG [org.jboss.ejb3.EJB3Deployer] create, openempi-ejb-2.0.5.jar
2010-09-10 11:03:31,910 DEBUG [org.jboss.ejb3.EJB3Deployer] Deploying: file:/C:/jboss/server/default/tmp/deploy/tmp4234392379439995465openempi-2.0.5.ear-contents/openempi-ejb-2.0.5.jar
Hold on... I might found the problem. It might be a typo in the source...
