Hi Patrick,
Being a WSIF developer I'm obviously a little biased, but if the choice is
primarily going to be on which is easiest I'd say go with WSIF.
The differences between AXIS and WSIF regarding ease of use are fairly
minor, you can use the classes and WSDL generated by WSDL2Java with both
AXIS and WSIF and once you understand how to use SOAP with either AXIS or
WSIF, then using the other is not so different.
Why I'd say go with WSIF is that it offers benefits that AXIS does not. It
allows you to change the WSDL binding the client uses so as to use
something other than SOAP, for example JMS or EJB, and this doesn't require
your client program to be rewritten. Even if you're sure your client will
only ever want to use SOAP what if you one day want to change the SOAP API
to be something other than AXIS? With WSIF you don't need to make any
changes to you client, just drop a new WSIF provider jar into the classpath
and you're client is using the new SOAP package.

Subject: Re: WSIF vs WSDL2Java question
Hi Anthony,
Thank you ... it answers to the question I asked but I actually wanted
to know more about WSIF before I go deeper into the documentation.
I haven't experiment this technology yet and it sounds interesting ... I
will have a look more seriously.
I had an other answer to my question that says that I can do it also
with the stub generated by WSDL2Java ... what I would want to know now
is which one is easier to use ... in other word do I need to learn WSIF
for achieving what I need to do?
Patrick.
