Why use SOAP in Java

[Sam Wun-4]

Hi,

I am wondering why use SOAP with Java?
Since SOAP is based on RPC, I think the best question may be asked, why use RPC for client-server application?

Thanks

Well... let's put it another way: Why not use SOAP and/or RPC for
client-server applications? Isn't RMI per definition also sort of RPC
if you keep it "straight" Java? Good thing about doing RPC in a
SOAP-like way is that you virtually can create a client-server system
without requiring any of the both parts to be implemented in Java, as
it is easy to, say, call server-sided Java "procedures" from a system
implemented in Python, .NET, Perl or whatever could come to your mind...

Cheers,
Kristian

I wonder if the real question here is not more like:  what advantage
does one gain in using RPC rather than some other method?  I must
admit that I sometimes ask myself that question.  I must also admit
that this whole thread is too general to be topical on the Tomcat list.

Web Browser ---(HTTP) ---  Tomcat Servlet/JSP

Java/C/VB/.Net Application  -----(Soap) ---- Tomcat Server (Axis)

Java Application ------- (RMI) ------- Application Server (Beans)

Browser Served Applications  -----(HTTP)------  Tomcat Harbor (Applications)

Its all related - protocols ontop of protocols, ie SOAP is an XML format
ontop of HTTP
And there is a lot of overlap, a programmer may decide to use a HTTP client
and call (POST or GET) for a simple value from a Tomcat, whereas SOAP would
translate parameters for you.

Probably the most general technology out there is browser against web
server, but sometimes the others are more useful... for example a remote
.Net programmer wants to call a function (web service) (soap) that you have
written in java on (axis) tomcat (in theory anyway).

But you need to study all these technologies because there is no perfect
solution.
Soap is quite slow, Ejb is hard to learn and servers are all different, but
well supported, Harbor is made by a crazy guy that loves Tomcat and doesnt
want to use anything else;)

If you can use a servlet (Tomcat) against a browser.... always a good
solution that one wants to move away from reluctantly... my feeling anyway.

Have fun...
