MBeanServerConnection - cann't invoke operation

[gmeroz]

Hi,
i'm trying to use the RMIAdapter for invoking mbeans operation from a java client.

i can not invoke the operation "showAll" of SystemPropertiesService.

i did manage to get the list of operation from this mbean.

this is the code i use:

Hashtable props = new Hashtable();
props.put(InitialContext.PROVIDER_URL, "jnp://localhost:1099");
props.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
MBeanServerConnection mBeanConnection (MBeanServerConnection)new InitialContext(props).lookup("jmx/invoker/RMIAdaptor");

mBeanConnection.invoke(new ObjectName("jboss:name=SystemProperties,type=Service"),"showAll",new Object[0],new String[0])

what's wrong here?

Try calling the same operation using bin/twiddle; show the exception
