    JBoss AS 7.1.3 - NullPointerException if an expression is in the jboss-app.xml file

    fmessiaen Newbie

      Hello everyone,

       

      A NullPointerException is thrown when the JBoss AS 7.1.3 tries to replace an expression in the "jboss-app.xml" file. (the "jboss-descriptor-property-replacement" property is set true in the "standalone.xml" file)

       

      Wolf-Dieter Fink says that the "jboss-app.xml" file should not contain expresssion (https://community.jboss.org/message/747278#747278), but a RedHat document say that the "jboss-descriptor-property-replacement", if set true, enables the properties replacement in the "jboss-app.xml" file. (https://access.redhat.com/knowledge/docs/en-US/JBoss_Enterprise_Application_Platform/6/html/Administration_and_Configuration_Guide/EnablingDisabling_Descriptor_Based_Property_Replacement.html)

       

      We want to avoid the use of the "default-distinct-name" property of the "standalone.xml" file. We have other deployed applications and we think that they does not have to manage a distinct-name if they does not declared one.

       

      One other point is that the property replacement works well in the JBoss AS 7.1.1

       

      Best regards,

       

      François

       

      The "jboss-app.xml" file:
