JAX-WS True/False?

Is this true?
Question1 :- A JAX-WS client can access a web service that is not running on java platform and contrariwise?

Question 2:- All session beans and MDB needs to have business interface?-->for this question answer is false, but my question is , in real bean projects in which scenario we need such kind of session beans without business interfaces?

Any highlights appreciated

I just split question 2 in two questions,

Question 2:- All session beans needs to have business interface?-->I think answer is true from usage point of view but from coding point of view is this mandatory to have business interface ?

Question 3:- All MDB needs to have business interface?-->answer is false

Hi!
Q1: Of course - this is the point of web services; to enable interaction in heterogeneous environments.
Q2: With EJB 3.1, there is the no-interface view which is a local view only accessible by components in the same application.
Q3: Message driven beans never have a business interface, since they are only accessible by sending a message (most commonly JMS) to a message queue or topic.
This is useful if you want a component with more loose coupling to its clients.
Best wishes!

Hi Ivan,

Q1 and Q3 -was very much crystal clear to me.
