Hi

If I have an mbean defined in application 1 and then use the mbean server in application 2 to invoke a method on the mbean, which class loader will the invocation happen in? app 2's classloader or app 1's classloader?

Hi Harry,

Clients cannot invoke methods on MDBs (this is why MDBs don�t have remote or home interfaces). They are strict server side components that act like asynchronous JMS listeners. Only the container calls the onMessage() if a message was added to the associate JMS destination. Clients interact with the MDB indirectly, sending JMS messages to the JMS destination.

Thanks for the reply Valentin, but I was referring to mbeans (as in jmx managed objects) not message driven beans.

It is sorta covered in the JavaRanch Style Guide.
