Creating a new binding

When tuscany was dropped in svn, I had written a new binding for ServiceMix.
I'm in the process of updating to latest tuscany svn head but it seems lots
of things have changed.

I'm basing the new code on the axis2 binding, but the problem i 'm facing
is my "binding.jbi" element is not recognized by the SCDL loader.
I guess I need to write an xsd and generate or manually write the new
classes in the org.apache.tuscany.model package, but I have no
found a way to make them recognized by the parser.
How can I accomplish that ?

Cheers,
Guillaume Nodet

Would it be easier to move this over to Tuscany? If this is a JBI
binding that allowed Tuscany to run in any JBI container then it would
have general applicability and by bringing it over we can help maintain
it as things change (given Tuscany's fairly volatile).

Would it be possible to handle this like our Tomcat integration where in
one case we have a generic J2EE mode which works with any web container
and in another we have a deep integration to Tomcat internals which
provides simpler configuration for users?

PS if you're not aware, we're currently discussing whether to stick with
this SDO based config loader or switch to a different one - it might be
worth hanging on a couple days or jumping in that discussion

Thanks, that was exactly what I was looking for.  I bet the line
   

SDOUtil.registerStaticTypes(ScdlFactory.class);

will save me :)

The code is available at http://svn.apache.org/repos/asf/incubator/servicemix/trunk/servicemix-sca/
but as Jim just said, it is based on code that is more than 2 months old and it seems I need to
rewrite it completely.

Thanks,

I believe they based the integration on what was there prior to the  
introduction of the new core architecture, including aggregates and  
builders. If I recall correctly, TuscanyModuleComponentContextImpl  
was used, which no longer exists.  The best place to start may be to  
look at some of the bindings and implementation types. There is an  
Axis2 binding and JSON binding as well as the Java and JavaScript  
types.  A couple of caveats, though:

- Changing the loaders to a StAX-based solution is under discussion
- Some of the bindings use a deprecated API, getAggregate(), that is  
going to be removed
- There will likely be some more churn in the core, although  
hopefully not to the extent that has been taking place

I need to do documentation on how parts of the extension model  
works...in the meantime, I'm happy to help as well answering any  
questions.

If you're code is available somewhere I'd be happy to have a look for what
you're missing.

At a guess, do you have a static initializer registering the SCDL factory?
If you've based your code on the Axis binding then you probably wont as its
built into the Tuscany core so doesn't need one, same for the Java
container. For one that works see:
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/binding.jsonrpc/src/main/java/org/apache/tuscany/binding/jsonrpc/loader/JSONRPCSCDLModelLoader.java
