[JBoss-user] mbean invoke getting ReflectionException

[G.L. Grobe]

I have a session bean calling invoke on a method in my mbean service that's getting a ReflectionException. If I leave Object[] and String[] as null, the call works fine. I've taken notes from a few archived posts about this, but to no success.   --- snip session bean code   public void scheduleTask(FieldObj fInfo) throws RemoteException { ...   List lServers = MBeanServerFactory.findMBeanServer(null);     MBeanServer lServer = (MBeanServer) lServers.get(0);     ObjectName name = new ObjectName("DefaultDomain:service=Scheduler");     Object[] args = { new FieldObj() };   String[] sig = { fInfo };     lServer.invoke(name, "scheduleJob", args, sig); ...   --- ServiceMBeanSupport      public void scheduleJob() throws Exception {       log.debug(Scheduler.class, "calling scheduleJob()");         return;    }      public void scheduleJob(FieldObj obj) throws Exception {       log.debug(Scheduler.class, "calling scheduleJob(obj)");         return;    }   --- ServiceMBean interface      public void scheduleJob() throws Exception;    public void scheduleJob(Object obj) throws Exception;   Any help much appreciated.
