    Jboss Classloader isolation not working

    venkaiah p Newbie

      I am using EJB2.1 Jboss4.0.2 and Xfire for webservices


      1. I set the below things for Jboss class loader isolation

      in JBOSS_HOME\server\default\deploy ear-deployer xml file

      &ltattribute name="Isolated"> true
      &ltattribute name="CallByValue"> true


      and in jboss-service.xml with below

      &ltattribute name="UseJBossWebLoader"&gtfalse



      2.In my application getting the local EJB proxy using the spring
      with the below code

      public static Object getEJB(String name, Class clazz)
      {
      // Look up the job slsb as a proxy factory bean.
      LocalStatelessSessionProxyFactoryBean bean = new LocalStatelessSessionProxyFactoryBean();
      bean.setJndiName(name);
      bean.setBusinessInterface(clazz);
      bean.setLookupHomeOnStartup(true);
      bean.setResourceRef(false);
      try
      {
      // Invoking after properties set ensure the lookup
      // is performed.
      bean.afterPropertiesSet();
      }
      catch(NamingException e)
      {
      logger.error("Naming Exception=" + e.getMessage());
      }

      // Proxy the factory bean to add the interceptor.
      ProxyFactory factory = new ProxyFactory(new Class[] {clazz});
      factory.setTarget(bean.getObject());
      factory.addAdvice(0, new TransactionFailureInterceptor());
      return factory.getProxy();
      }

      and while getting the proxy of the bean using the below code
      ProcManager ProcManager = (ProcManager) BeanUtil
      .getEJB("ProcManagerLocal", ProcManager.class);

      where ProcManager is the interface commonly implemented by both Service class and EJB and this service class is exposed as a webservice using xfire over spring configuration.


      3. With these configurations the application is getting deployed but a method call on the EJB throught service impl is throwing the below error

      NoSuchMethodExceptionCaused by: java.lang.NoSuchMethodException: $Proxy104.logon(com.to.Logon)

      3. Can some suggest on how to resolve this...

      thanks in advance
