Hi all,
I have a pojo that tries to invoke a method on a service (i lookup the service
and then perform the invocation).
I get the following exception:
14:31:00,125 INFO [STDOUT] Getting job
14:31:00,391 ERROR [AMSAddContentRequest] Error during adding content

However, this pojo is used from inside a session bean. When I perform
dependency injection inside the bean, and pass the injected service as
parameter to the pojo, the method gets activated.
I have no ClassCastException or NullPointerException in the lookup, here is the
lookup code:
String providerURL = AMSConfigurationProxy.getAMSConfiguration().getHost() +
":1099";
Hashtable props = new Hashtable();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(InitialContext.PROVIDER_URL,providerURL);
InitialContext ctx = new
InitialContext(props);
MBeanServerConnection mbsc =
(MBeanServerConnection)ctx.lookup("jmx/invoker/RMIAdaptor");
ObjectName objName = new
ObjectName("ams:service=contentPriorityManager");
manager =
(ContentPriorityManager)MBeanServerInvocationHandler.newProxyInstance(mbsc,
objName,ContentPriorityManager.class,false);
Can you please help me understand why i cannot activate the method "add" after
the lookup?
(I'm using jboss 4.0.4GA)
Thanks
