    wierd isolated class loading behaviour Jboss 4.2.3

    ozyman Newbie
      Hello people,
      I'm struck with an isolated class loading problem in Jboss and I can't seem to find a solution. More over I can't seem to understand the behaviour of Jboss(verion 4.2.3), which is making finding a solution all more difficult. I'll be really thankful if anyone can tell what's really going on. Here is my case,
      I have a .ear and .war to be deployed into the server. For obvious reasons, we use isolated class loading to avoid the conflicts. I used this guide to follow the isolation: http://community.jboss.org/wiki/ClassLoadingConfiguration
      Here are the jboss-app.xml and jboss-web.xml files of my .ear and .war

      Hello people,

       

      I'm struck with an isolated class loading problem in Jboss and I can't seem to find a solution. More over I can't seem to understand the behaviour of Jboss(verion 4.2.3), which is making finding a solution all more difficult. I'll be really thankful if anyone can tell what's really going on. Here is my case,

       

      I have a .ear and .war to be deployed into the server. For obvious reasons, we use isolated class loading to avoid the conflicts. I used this guide to follow the isolation: http://community.jboss.org/wiki/ClassLoadingConfiguration

       

       

      Here are the jboss-app.xml and jboss-web.xml files of my .ear and .war

       

       

       

      <?xml version="1.0" encoding="UTF-8"?>
      <jboss-app>
         <loader-repository>com.xxxx:loader=XXXX-loader</loader-repository>
      </jboss-app>
      

       

       

      <?xml version="1.0" encoding="UTF-8"?>
      <jboss-web>
          <context-root>itmWebservices</context-root>
        <loader-repository>com.xxxx:loader=XXXX-loader</loader-repository>
          </jboss-web>
      

       

       

       

       

      Initially we used the <class-loading> tag around <loader-repository> tag in jboss-web.xml file. This used to give errors while deploying. So, after reading the guide, I mentioned above, I removed the <class-loading> tag and it seems to deploy fine. No errors while deploying. But when I try to connect my .war to .ear, I get the following error

      which means, as far as I understand, that the deployment is not clean or the class isolation is not being done correctly. What could be a possible explanation and a solution?

       

       

      I even tried using the global class isolation, by editing the deploy/ear-deployer.xml and setting class isolation and call by value attributes to true. Even they don't seem to do the thing.

       

       

      Thanks in advance
