how to get a user definition object invoked by mbeanserver in web service
I just can't cast the returned object to my defined object

the mbean implemetation:
public class ModelService extends ServiceMBeanSupport implements ModelServiceMBean {
  |   public ModelObj getModelObj(String id) {
  |     ModelObj obj = new ModelObj();
  |     some action here;
  |     returen obj;
  |   }
  | }
ModelObj is a simple pojo I defined,there're only some getter and setter
the mbean definition:
<mbean code="jboss.mbean.model.ModelService" name="jboss.momo:service=ModelSvr"/>
the web service method code as follows:
public String getModelName(String id) {
  |   try {
  |     MBeanServer server = org.jboss.mx.util.MBeanServerLocator.locateJBoss();
  |     Class clazz = server.getClassLoaderRepository().loadClass("jboss.mbean.model.ModelObj");
  |     ObjectName oname = new ObjectName("jboss.momo:service=ModelSvr");
  |     String[] sig = { String.class.getName() };
  |     Object[] opArgs = { new String("A01") };
  |     Object result = server.invoke(oname, "getModelObj", opArgs, sig);
  |     ModelObj mo = (ModelObj)clazz.cast(result);
  | ///////some thing error,I wanna make the return object to cast to my defined object to invoke more operation,but just here comes some error "java.lang.ClassCastException: jboss.mbean.model.ModelObj"
  |     return mo.getName();
  |   } catch (Exception e) {
  |     e.printStackTrace();
  |     return null;
  |   }
  | }
the web service definition:
<service name="ModelSvc" provider="java:RPC">
  |   <parameter name="allowedMethods" value="*"/>
  |   <parameter name="className" value="webservice.services.ModelParser"/>
  |   <beanMapping languageSpecificType="java:jboss.mbean.model.ModelObj" qname="ns7:ModelSvc" xmlns:ns7="ModelSvc"/>
  | </service>
when in other client(command line run mode)
Object result = server.invoke(oname, "getModelObj", opArgs, sig);
can be write like this:
//MBeanServer server = org.jboss.mx.util.MBeanServerLocator.locateJBoss();
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "10.1.0.2");
Context iniCtx = new InitialContext(env);
RMIAdaptor server = (RMIAdaptor) iniCtx.lookup("jmx/rmi/RMIAdaptor");
ModelObj result = (ModelObj)server.invoke(oname, "getModelObj", opArgs, sig);
this will not throws java.llang.ClassCastException
