Subject RE: [WSIF] [PROPOSAL]Additional contribution ... JCA (J2C) provid er
Date Wed, 30 Oct 2002 15:31:20 GMT

I checked quickly on without finding any
documentation about the JCA provider for WSIF.
Any idea where I can find that?

We are currently creating an application (J2EE application with embedded
Axis) to allow an end user to expose some pieces of our existing
application(s) as Web Service (the J2EE application will create new Web
Services). So far, only SOAP over HTTP is supported, but we start getting
some request for a java interface which is not going through HTTP and the
SOAP marshalling/unmarshalling. We are currently considering some type of
EJB interface to the service.

We are starting to seriously consider the use of WSIF to generalize the idea
but I am trying to understand the scope of WSIF and if anyone else is doing
similar things that I should look at, if this is something that will be
standardized at some point.
Here is a first set of questions I am trying to answer. Any help will be

1) When writing a new WSIF provider, does is also mean defining the
corresponding WSDL extension (like the EJB ones that I saw in Axis
documentation)? This is why I wanted to get some documentation on the JCA
provider to see if it defines this part as well.

2) If WSIF implies WSDL extensions, who (if anyone) is working/pushing to
have those extensions standardized? Any vendors?

3) Does implementing a WSIF provider also mean the creating of some type of
tool like WSDL2Java (or may be an update to this tool) to understand the
WSDL extensions and generate the client and/or server stubs/skeleton?

4) WSIF is a pure Axis/alphaworks project so far. Any actions to make it
some kind of a standard?

Some of those questions might not make too much sense as I am just starting
to educate myself on WSIF.
