      Hi

      I have a JMS listener service deployed on Jboss. this is the log generated when i start jboss server.

      This service is listening messages from other application. As soon as this service receives a message it calls a ejb which is deployed as EAR in weblogic server instance. I have a service locator class which is getting the reference of home interface of the EJB.

      I am not able to get this thing working.The error I am getting is.

      As far as understood it. the problem is due to class between different class loaders.I am confident about this as I tried doing this in my class.


      logger.debug("this.getClass"+this.getClass().getClassLoader());

      and response i got is:

      org.jboss.mx.loading.UnifiedClassLoader3@1a6a1a7{ url=file:/D:/jboss-3.2.5/server/default/tmp/deploy/tmp23532tmeformjmx.sar ,addedOrder=9}

      AND when i tried this.

      logger.debug("o.getclass"+o.getClass().getClassLoader());

      i got this response..

      weblogic.utils.classloaders.GenericClassLoader@1c3fd59 finder: ServletClassFinder(http://10.0.3.141:9001/bea_wls_internal/classes/_appsdir_TMEFORM_ear%40/)

      Please suggest a solution for this problem.
