    Problem setting a dependency in a MBean ear

    Alvaro Torres Newbie

      Hi Jboss community,

       

       

      I am running with JBoss 7.0.2 and have a MBean in an ear, which is using a datasource. And the MBean will also use the datasource in the stop method. I would therefore like to add a dependency in the jboss_service.xml file where the MBean is configured, but I do not know how to do this in JBoss 7. I hope this is still possible as in previous releases of JBoss as I am getting a NullPointerException when stopping JBoss. And from what I can see then this is because the service 'PropertiesMgmtSecurityRealm' is stopped before the MBean stop method is called.

       

      The Datasource configuration looks the following way:

       

      <datasource jndi-name="java:/test/jdbc/defaultDB" pool-name="defaultDB" enabled="true" jta="true" use-java-context="true" use-ccm="true">

                ….

                          <security>

      <security-domain>

      TestDSEncryptDBPassword

      </security-domain>

      </security>

                ….

      </datasource>

       

      I then thought that the MBean configuration should have looked the following way:

       

      <mbean code="test.TestManager" name="Test:name=TestManager">

      <depends>jboss.jca:service=DataSourceBinding,name=java:/test/jdbc/defaultDB</depends>

      </mbean>

       

      The NPE is as follow:

      Anybody can help me here?

       

      Thank you,
