To Soap or not to Soap!
Hello there!
I would appreciate your comments on the following. I am looking forward to building a full featured Java Application, to be deployed through the web Using JavaWebStart. The application is to behave as a front end to an application running on a server. What options do I have for the communication between the front and the back end if it has to go through internet firewalls and routers.
Best Regards
Ramon

Subject: RE: Design Pattern
I might have not explained my self correcly, I am concerned with the value objects being the same, not the service objects. For instance, having a Person object that is an argument to soap methods, the Person object could have a calculateAge() method, which is apropiate for me to call on the server or on the client. If I do a bean mapping, methods other that JavaBean getters and setters get removed, althoug they are apropiate for me to call on the client.

Subject: Re: Design Pattern
As long as you keep the Subjects on client and server, why should not be
possible?
(you have the same methods on client and server, the same class names if you
decide to keep the same structure and so on...) .
I might not have understood the question ...
