EJB web service endpoint registration NPE

[whitingjr]

Hi,

  I have an JEE application based on JEE5 spec. Bundled are some ejb3 SLSB. One is annotated with webservice. When AS7 starts up it is throwing an error when it attempts to register the endpoint.

In webservices/server-integration/src/main/java/org/jboss/as/webservices/deployers/WSIntegrationProcessorJAXRPC_EJB.java the newEjbEndpoint(final PortComponentMetaData portComponentMD, final EEModuleDescription moduleDescription, final Set<String> securityRoles) method gets the interface class name by calling portComponentMD.getServiceEndpointInterface().

The value returned is null. So this null passed on the next line to sessionBean.addWebserviceEndpointView(seiIfaceClassName)  causes the following NullPointerException stack trace.

I am using a as7 build from master branch. As of 22 Tue 2011.

Hi Jeremy,

using a JBoss AS which is built from a dev trunk might be not such a good idea...nevertheless it looks like, there is a problem resolving the ServiceEndpointInterface. Either specify the annotation property endpointInterface or post some code.

Best regards,

Mark

That null check should happen at some place for sure - for a better exception. I'm not sure why the WS metadata is returning null in first place. Please file a JIRA.

Hi Jaikiran,

  JIRA raised.

Thanks Jeremy. Any chance you can provide more info on the deployment (ws endpoint annotations, descriptors if any, etc.) If you could even provide the deployment for reproducing this issue, that would be great.

Hi Alessio,

I am creating a test case to replicate the exception. When complete I'll attach it to the JIRA.

Hi Alessio,

  I have added a sample project to the JIRA which replicates the issue when deployed.

It looks like the endpoint deployer is not detecting when the ejb jar descriptor file does not have an entry for the ejb. Which is valid when the descriptor file can define other things like MDBs.

Thanks Jeremy,

we'll have a look and fix the issue.
