与JBoss的Mbeans

我正在尝试调用部署在JBoss中的MBean，但我遇到了这个异常：

我正在使用JBoss 5.1.0GA，客户端代码是

Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
            env.put(Context.PROVIDER_URL, "jnp://localhost:1099");

            InitialContext ctx;
            ctx = new InitialContext(env);

            MBeanServerConnection server = (MBeanServerConnection)ctx.lookup("jmx/rmi/RMIAdaptor");


               // get reference to CacheMgmtInterceptor MBean

              String cache_service = "jboss:service=JNDIView";
               ObjectName mgmt_name = new ObjectName(cache_service);
               System.out.println( server.getMBeanInfo(mgmt_name).getClassName());
               Object[] obj = new String[1];
               obj[0]= new String("hello Sapo pepe");
            Object temp = server.invoke(mgmt_name, "sayHello", obj, new String[]{"String"});
            System.out.println(temp);

我可以访问抛出JBOSS JNDI-Console，因此MBean正在运行 . 提前致谢
