Looks good. I even managed to get the Eclipse based tool up and running, with little problem guessing how to use it.
Even managed to generate empty BPEL&WSDL & JBoss Java classes from my .cdm file ;) What's needed next is simple example .cdm file to help learning.
Looks great! As jarkko wrote, a small tutorial or example on how this can be used together with JBoss ESB would be great!
All things come to those who wait ;-)
