I've been attempting to create a webtools-style faceted project that will mimic an EJB or Web project in ui and functionality to discover all that is involved in the process and, once successful, potentially use this infrastructure to create further project types.
To compare, I created an EJB project with an associated EAR, and compared it with my project type (an EJB 3.0 implementation) and an EAR for that as well. The EJB projects themselves and their .settings/* files matched almost identically, as was expected.
I'm fairly unfamiliar with the component core APIs so this is new ground for me. I'm curious if anyone knows where the webtools ear got that line, while mine did not. It's possible I missed some line when copying webtools code, but I'm unsure of even the API to modify this file so I'm not sure what to look for.
