Inteceptor not being called

[andrewboyd]

Hi all,
I have a class that extends ServiceMBean that has an Inteceptor
that extends AbstractInceptor that never seems to get called.

MBean Class:

public interface ParsingAgentMBean extends org.jboss.system.ServiceMBean {

 com.digitalreasoning.kdas.Message parse(com.digitalreasoning.kdas.Message msg) ;

jboss-service.xml:

 <mbean code="com.clarity.cpin.agent.ParsingAgent"
 name="drs.kafe:type=LocalAgent,name=ParsingAgent">
 <depends>drs.kafe:type=Host,name=Host</depends>
 <descriptors>
 <interceptors>
 <interceptor code="com.digitalreasoning.kdas.util.rtfConverter.RTFConverterInterceptor"/>
 </interceptors>
 <persistence persistPolicy="Never"/>
 <currencyTimeLimit value="10"/>
 <state-action-on-update value="keep-running"/>
 </descriptors>

 </mbean>

 <mbean code="com.clarity.cpin.agent.ParsingAgentTester"
 name="drs.kafe:type=LocalAgent,name=ParsingAgentTester">
 <depends>drs.kafe:type=LocalAgent,name=ParsingAgent</depends>
 </mbean>

I'm calling it just for testing from the startService method in ParsingAgentTester.
calling code:

 logger.debug("Starting Service");
 ObjectName parseAgentName = new ObjectName(ParsingAgent.OBJECT_NAME_STR);
 MessageFactory msgFac = MessageFactory.getMessageFactory(2, new String[]{"dummy1","dummy2"});

 Message msg = msgFac.createMessage(null,"This is a message");
 System.out.println("Is ParsingAgent registered? : "+mBeanServer.isRegistered(parseAgentName));
 logger.debug("Calling ParsingAgent.parse(msg) via MBeanServer");
 mBeanServer.invoke(parseAgentName,"parse", new Message[]{msg},
 new String[]{Message.class.getName()});
 super.startService();

std out:
15:58:37,785 DEBUG [ParsingAgentTester] Starting
15:58:37,785 DEBUG [ParsingAgentTester] Starting Service
15:58:38,035 INFO [STDOUT] Is ParsingAgent registered? : true

I've put print outs that is called from the constructors of the inteceptor:

public class RTFConverterInterceptor extends AbstractInterceptor{

 private RTFParser converter;

 public RTFConverterInterceptor(){
 super();
 createConverter();
 }

 public RTFConverterInterceptor(String s){
 super(s);
 createConverter();
 }

 public RTFConverterInterceptor(MBeanInfo mBeanInfo, MBeanInvoker mBeanInvoker){
 super(mBeanInfo, mBeanInvoker);
 createConverter();
 }

 public Object invoke(Invocation invocation) throws InvocationException{
 String opName = invocation.getName();
 System.out.println("RTFConverterInterceptor opName : "+opName);
 // If this is not the invoke(Invocation) op just pass it along
 if(opName.equals("invoke") == false){
 return getNext().invoke(invocation);
 }

 Object[] args = invocation.getArgs();
 // Do our stuff here.
 //converter.reinitialize();

 return getNext().invoke(invocation);
 }
 private void createConverter(){
 System.out.println("Creating RTFConverter");
 converter = RTFParser.createParser(new InputStreamReader(System.in));
 }
}

The stack trace does not show any indication of the inteceptor and there
is no output from it. I have a feeling the NPE probably hase something
to do with the missing inteceptor.

Any Suggestions?

Thanks,

Andrew

Only xmbeans support interceptors, not standard mbeans. See the xmbeans such as JNDIView found in the 3.2.3 release which has:

 <mbean code="org.jboss.naming.JNDIView"
 name="jboss:service=JNDIView"
 xmbean-dd="resource:xmdesc/JNDIView-xmbean.xml">
 </mbean>
