Hi Martin, Good findings.
I skipped the instructions to delete ejbModule/META-INF/openejb-jar.xml during my testing so it worked well. If I delete this file I can reproduce your exception in my environment. I opened two JIRAs. 1. https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-689 NullPointerException when publishing with Geronimo Eclipse Plugin v2.1.7 (I think it needs either code or document update or even both) 2. https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-690 NullpointerException occurs if one adds a "Utility Project" to the EAR Thanks very much for catching the problem. -- Best regards, Han Hong Fang (Janet) hanhongfang AT apache.org
