timing on need for JAX-WS and JAX-B support
Hi Guys,
Can you give an indication of when you expect to go for J2EE 1.5
certification and hence require JAX-WS and JAX-B support from Axis2?
Getting some indication of the timing will help us prioritize and target
it to a specific version of Axis2. (We're not putting it into 1.0; hence
the question!)

I'd love to work on JAX-B but there are only so many hours in the day :(

I see two possible strategies here:
1) retrotranslator.sourceforge.net - build time or runtime
translation from Java 5 byte code to Java 1.4 byte code. Strangely
enough, it seems to work perfectly (including debugging). FWIU, the
conversion from 5 to 1.4 is a fairly trivial 1-to-1 translation.
Baisically, it removes the new extra op code in Java 5 and remaps new
apis in the java.* packages to apis in net.sf.retrotranslator.runtime.*.
2) abstraction layer - the main code is written in Java 1.4 and there
is an abstraction layer that deals with the Java 5 spcific bits like
looking up annotations.
James Strachan has done some extensive testing with retrotranslator
(including the JAX-B ri) and really wants to use it. I think option
2 will work but will require a ton of work, so I'm leaning towards
option 1. My gut says that option 1 will make people nervous at
first, but once they see it working, I think they will learn to love
the bomb ;)

We've done our own partial schema to Java mapping thing (called ADB ..
Axis Data Binding) that covers maybe 80% of schema.

We haven't committed to doing JAX-B yet but there's been some interest.
We've started on SAAJ and JAX-WS but not specific timeline yet.
One concern with JAX-B is that its J2SE 1.5 specific and we want to
continue to run under 1.4. I'd be interested in understanding the
Geronimo 1.4/1.5 strategy.

That's a good question. Having just started looking into this
recently, I don't have a handle on that yet. Part of the work involved
is getting through the 375 page spec ;-).
The other concern I have is how changes to support the JAXB spec will
affect the database side of Castor. I've been thinking that starting a
Castor 2 branch would be a good idea and do all of the work in there -
kinda like what David did with OpenEJB 2. It would also make it easier
to know that Castor 2 supports JAXB 2.

I agree - it's a good starting point.

You guys already support fancy-pants mapping. How soon do you think
you could get that part into the 80% compliant range?
That'd at least be enough to get started.

A couple of weeks ago I began investigating what it will take for
Castor support the JAXB 2 API on top of the existing engine. It's
certainly doable with one issue being the ability to cover the entire
spec in a timely manner if I'm the only one working on it. There are
certainly other concerns, but that's the biggest one at the moment.

I could use jaxb support now. I'd like to use it instead of castor
or xmlbeans for marshalling deployment descriptors -- or rather with
castor or xmlbeans if either of them implement jaxb.
I didn't know Axis2 was going to implement jaxb. Are the xmlbeans
guys going to implement it too?

Hi Sanijva,
I alone wish to know when we're going to support Java EE 1.5. I don't
remember any discussion about an exact timeframe or anything alike,
but I wouldn't be mistaken saying all of us would be interested in
doing it as soon as possible. I think we need to read the spec from
cover to cover, divide it on short and simple tasks, create them in
JIRA and move on (how simple it was to write it ;)).
As Dave B. already said, there's some interest in using JAX-B in
OpenEJB 3 to handle xml files. I don't know it at all, and am going to
read over the JAX-B spec soon. I think that the sooner the spec will
be available in Axis2, the better.
