Business tier objective 4.3 is as follows:

"Explain how Java EE supports the deployment of server-side components implemented as web services and the advantages and disadvantages of adopting such an approach."

Seeing as this is a business tier objective I�m assuming they�re talking about the JAX-RPC and JAX-WS stateless session bean programming models. But when they talk about advantages and disadvantages there has to be a comparison involved somewhere.

How are other people interpreting this? Is it meant be a comparison of the advantages/disadvantages of the servlet/stateless session bean programming models?

Any thoughts would be welcome.

Kind regards,

Jonathan

Considering Deployment = Usage, You can use SSB and POJOs to create Web services. None of the design patterns I came across have used Servlet as a WS end point (Please let me know if you have come across any such case) JAX-RPC and JAX-WS are the technologies used to by the app server internally so this question is about SSB and POJO from my point of view.

Based on Whizlabs mock exams, the questions seem to be about @WebService and @WebMethod annotations.

This is true. I've been looking at the ePractice questions from Sun for this objective; they also center on JAX-WS specification in one way or another.

One possible comparison I think would be
Contract Last approach vs. Contract First approach.

Look at Spring Web Services.
