MBean operation return error?

Hi,

I am working with the MBean and deployed to the JMX server.
One of the operations (methods) return object data type.
One with string/integer/boolean works fine and return the result.
But when the return type is object type, it fails.

Why is it doing that?
What do I need to do to fix it?

The error says:
Problem invoking getxxxxx():java.rmi.unmarshalException: errror unmarshalling return;
the nested exception is: java.io.writeaborstedExceptin: writing aborted;java.io.notserizableexception


mbean.setxxxDao(svcxxxDao);
		ObjectName name = new ObjectName(
				"xx.xxx..mbean:type=ServiceCatalog");

		mbs.registerMBean(mbean, name);
		 System.out.println("Waiting forever..."); 
	     Thread.sleep(Long.MAX_VALUE

Open in new window

);

What kind of object does Mbean return?

In EJB world we used to get unmarshalException when we were expecting an object for a custom class (ie. Emplolyee, User, Subscriber) which didn't implement the Serializable interface.

Check at your end, bcaz the object that you are expecting is not implementing Serializable interface. It mentioned in the exception.
"java.io.writeaborstedExceptin: writing aborted;java.io.notserizableexception"

Thank you for your answer.
My custom class did not use the Serializable.

 I will try that when I get back tomorrow.

Still getting this error after making it Serializable and also now it is complaining  that object data type class not found error.

Problem invoking getxxxxx():java.rmi.unmarshalException: errror unmarshalling return
ClassNotFoundException.

Do I need to make these class as MBean also?
