Hi All,
I am having trouble generating an emf model from annotated java. I was
able to follow the tutorial on generating an emf model from existing java
code with no problems.
Excited, and perhaps overly optimistic, I went through my existing code
base adding @model tags to everything that looked relevant. Afterward, I
followed the steps again, but this time no dice. Everything went exactly
as in the tutorial, but when I got to the "Package Selection" screen,
there was just an empty box.
I have tried all kinds of things, but nothing seems to work. Just for
grins, I tried importing a very simple java model and, again, it worked
fine. So, I'm thinking there is something simple I'm missing on the big
model. Any ideas?
Unfortunately, my company is pretty paranoid about its intellectual
property, so I can't attach any actual code. I know that's severely
limiting, but I was hoping someone has seen this already and knows "all
you have to do put the whatchamacallit on the whozit, click your heels
three times and sacrifice a free-range chicken." If this doesn't go
anywhere, I can try to fabricate an example that also doesn't work. It
occurs to me, though, that if I can successfully pull that off, I will
probably have figured out the solution.
Thanks,
Ashley
PS - I have searched the web and this newsgroup extensively and none of
those threads have helped.
PPS - I have a fresh installation as of about three days ago, so I'm
pretty sure it's not a stale software problem.
PPPS - Installations on both Windows XP and Mac OS X have resulted in the
exact same results (both successful and unsuccessful).

Perhaps there was some unexpected problem encountered. Did you check
the Error log?

If you care to set it privately I can look at it but otherwise I need
something to go on to fix any lurking bugs.

Yes, you might want do start with one file at a time...

I'm happy to help if I can reproduce. At least if you can track down a
stack trace in the error log, I'd have some tea leaves to read.

Ashley,
I think MoDisco can create UML which you can map to Ecore, but
ultimately for any EClass, EMF will want to generate an interface and an
implementation class... I think that specifying @model kind="class"
will help convince it to map to an EClass, but as I said, it won't
generate a class in the end...
