    ClassCastException: org.jboss.cache.pojo.impl.PojoCacheImpl cannot be cast to org.jboss.cache.pojo.PojoCache

      Friends,

      I am using Pojo Cache first time. I'm getting ClassCastException: org.jboss.cache.pojo.impl.PojoCacheImpl cannot be cast to org.jboss.cache.pojo.PojoCache while I try to retrieve an instance of PojoCache using following code.

       

      MBeanServer server = MBeanServerLocator.locateJBoss();

      ObjectName on = null;



      try {

      on = new ObjectName("jboss.cache:service=PojoCache");

      } catch (MalformedObjectNameException e) {

      logger.error("The format of the string does not correspond to a valid ObjectName.", e);

      } catch (NullPointerException e) {

      logger.error("An application attempts to use null in a case where an object is required.", e);

      }

       


      PojoCacheJmxWrapperMBean cacheWrapper = (PojoCacheJmxWrapperMBean) MBeanServerInvocationHandler.

      newProxyInstance(server, on, PojoCacheJmxWrapperMBean.class,false);


      PojoCache pojoCache = cacheWrapper.getPojoCache();

       

       

      Below is the cache configuration file I'm using. This file is copied to 'deploy' directory of 'default' server.

       

       

      pojocache-jboss-beans.xml
      <?xml version="1.0" encoding="UTF-8"?>
      <deployment xmlns="urn:jboss:bean-deployer:2.0">

      <property name="configuration">
      <inject bean="CacheConfiguration" />
      </property>
      </bean>
      </deployment>

       

      Please help to resolve this.

       

      Thank you.
