Hello,
Raymond, thanks for your answer. I've checked my mail late, I see
that you can test my example without my source files.
At the moment, I commented the service promotion as you suggest, and I'm
trying to download the latest 1.5 code
but I can't found that.
Someone here knows how to download that version? I was reading
Continuum<http://vmbuild1.apache.org/continuum/projectView.action?projectId=277>and
in version says "1.6-SNAPSHOT" .
Have Tuscany SCA version 2.X implemented the same functionality that version
1.x?
Raymond, will I found my errors fixed in version 2.X?
Thanks,
Sebastián Groh
