Yes we would, and that is really scary and in principal I agree with
you.
What I was after (I think ;-) was that when we begin talking about
webservices we are trancending what the JBoss developement hav been
about: doing the best implementation of a bunch of Java API for
enterprise development. As far as I know all the "publisher" API:s of
JBoss are Java standards.
The only "external" API we produce that is not for Java is actually HTTP
(HTML and custom XML perhaps, which by definition will be decided by the
developers and his/hers requirement).
Whith webservices we actually get two types of standards/specifications
to look out for:
- The XML standards, such as SOAP, XP, ebXML, UDDI, WSDL. Since these
will be actually be external API the decissions on wich spec to
suppport is important, but verry hard.
- Java API:s for the XML standards. Should we follow the way JBoss has
hierto worked the focus should be on integrating the Java standards
that becomes available to handle XML. Here we may either do as for
example with Java Mail (use the Sun implementation), Tomcat/Jetty
(use a nother open source implementation of the spec) or EJB/jndi/jms
etc (write a spec compliant implementation our self).
I do think the focus for JBoss ought to be on getting good
implementations of the Java standards, and write them our self if we
need too.
It's a shame that the JSR implementations available is not possible to
use.
Why not start by the question: what would be most usefull to developers?
- Do they need help with setting up a registry where they may register
there XML based services, or will most project do that exchange
manually?
- Do they need help with transforming EJB interfaces to a WDSL based
description they may register in a register, or do they write their
webservices as servlets.
- Do they need help with XML messaging (a XML message servlet and MDB
and deployment of these).
- Or do they only need a SOPA library and want to do everyting on their
own.
My personal view would actually favor XML messaging. I thing that an
early atempt to make JAXM available in JBoss would we worth the work.
But then again, someone would have to do that work...
