    MDB With Ear Isolation

    Stephen Campbell Newbie

      Hi Folks,

      I have an MDB deployed which reads off a queue happy as larry, what i need to do now is deploy a new version of this MDB that will run side by side on the same domain as the old one (listening to different queues obviously).

      When i first started everything up the new MDB was using the code in the old ear, grand, what i thought to do would be to turn on ear isolation on the domain.

      The steps i have taken are as follows:-

      First, edit the conf/jboss-service.xml file and set the NamingService CallByValue to true:


      Second, edit the deploy/ear-deployer.xml file and set the Isolated and CallByValue attributes to true:

      Last, edit the deploy/jbossweb-tomcat50.sar/META-INF/jboss-service.xml file and set the Java2ClassLoadingCompliance and UseJBossWebLoader attributes to false:

      However when i deployed the MDB i get the following error :-

      I have tried other methods, i.e. using the jboss-app.xml to make only that individual ear isolated, depending on what way i package the mdb with this file added one of two things will happen

      1) The Ear starts with no error, but the mdb.jar does not get deployed
      2) I get the following error :-
