Hi Kurien,

I am not able to find any design consideration in this case that
specifically favor either RMI or WS. From that point of view, I think
either of them would be alright.

In my opinion, WS would be a better choice because it reduces the
coupling between the modules and provides higher extensibility. AFAIK,
SOAP does not have any scalability issues. I have used WS to pass large
amount of data (not more than 100K), but did not observe any big issues.
Moreover since it uses HTTP, you do not have to setup an additional
tunnel. Therefore from a security point of view also you might not end
up with any concerns if you use WS. But here, if the server needs to
push some data without the client requesting for it, WS cannot work for
you.

Hope this enhances your decision process

Jaise

Subject: Design Question RMI or WebService

Hi Folks,

I have a design question where I would like some feedback. I
want an applet to communicate an J2EE server behind a firewall. The
scheme of communication between these two entities will be push and pull
(where applet can push and pull data from the J2EE server).

At one time I had implemented RMI mechanism but it was a situation
without firewalls. I know that through RMI you can tunnel across
firewall.

Which of these two schemes is the best?

* .Use RMI to have applets call EJBs ?
* Use Webservices to implement SOAP between applet and EJB?

Another requirement is that the data passed between the applet and J2EE
server is considerably high. I have heard arguments that using SOAP will
not scale well.

Is there any alternate option than the above?

Thanks

Kurien
