Lars Vonk commented on JBAS-7211:
---------------------------------

I solved the EJB implementation class error message by specifying the ejb implementation class in ejb-jar.xml. In 4.2.3 this is apperantly not a problem.

After fixing this the application deployed okay with the following WARN message:

14:21:30,120 WARN  [HDScanner] Failed to process changes
org.jboss.deployers.client.spi.IncompleteDeploymentException: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):

DEPLOYMENTS MISSING DEPENDENCIES:
  Deployment "jboss.j2ee:jar=certification-war-0.7-SNAPSHOT-development.war,name=ResourceLookupServiceBean,service=EJB3_endpoint" is missing the following dependencies:
    Dependency "jboss.j2ee:jar=certification-war-0.7-SNAPSHOT-development.war,name=ResourceLookupServiceBean,service=EJB3" (should be in state "Configured", but is actually in state "** NOT FOUND Depends on 'jboss.j2ee:jar=certification-war-0.7-SNAPSHOT-development.war,name=ResourceLookupServiceBean,service=EJB3' **")

DEPLOYMENTS IN ERROR:
  Deployment "jboss.j2ee:jar=certification-war-0.7-SNAPSHOT-development.war,name=ResourceLookupServiceBean,service=EJB3" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.j2ee:jar=certification-war-0.7-SNAPSHOT-development.war,name=ResourceLookupServiceBean,service=EJB3' **

I think this is caused by the fact that we have packaged the ejb-jar in the WAR file (this is accidental).

So to summarize what happened IMHO:

The NullPointerException when deploying the WAR file was caused by the fact that the ejb-class tag was missing in the ejb-jar.xml. Enabling java assertions for jboss gave a more specific error message.
