Hi Bogdan,

Nice to hear you again. Are you willing to contribute to SCA Tools? ;)

Did you successfully add your new binding?

As Vincent said you, currently, there is no documentation but you can 
have a look at the Frascati and Tuscany plugins. To resume, there are 
two steps:
- First, create a new plugin where you define a new ecore that extends 
the SCA MM. Then, generate the code. The namespace mustn't be the open 
SOA one.
- Then, create a new plugin (...diagram). Edit the plugin.xml file and 
add the extension points needed to add your new SCA elements in the SCA 
Designer. You can also use the creation wizard (SCA Diagram Extension) 
that generates this plugin. I recommend you to write directly the 
plugin.xml file because this wizard isn't yet stable...
That's all.

If you want, you can explain the procedure on the wiki [0]. All the 
contributions are welcome ;)

Concerning the possibility to change the shape, we didn't work on this. 
You're the first that get onto this. I think that it can be an 
interesting feature and not very hard to implement.

In addition, we received a contribution, one month ago, that allows to 
introspect Java code (only POJO, not EJB as you made). We have a first 
prototype where we can construct SCA assembly file in a bottom-up 
manner. Some paperwork from the contributors are missing before I can 
commit the code... I though this contribution can interest you.

Concerning the svn, did you use [1]?

Best regards,

Stephane Drapeau
