"This papyrus add-in introduce C and C++ code generation ability to the tool. C++ code generation rely on JET templates, and C code generation feature is based on Acceleo..."
What does "C++ code generation rely on JET templates" mean? Do I need to install plug-ins for JET? Can you please list out the required plug-in for C++ code generation (or a short description on how to do it)?
We (CEA LIST) ported the jet based C++ generator that was available as extension for Papyrus 1.12.x to the new version of Payprus. This generator is currently used within a different project (eC3M) and will propably be available in Spring 2012.
I'm not sure, if I got your last message right: "The standalone version does not have C++ codegen. I downloaded eclipse galileo and papyrus."
Does it mean, you're now using the Papyrus 0.7.x/0.8.x from eclipse.org or still the older Papyrus 1.12?
In case of the latter, you can install the code generation add-in using the update-site
