Thanks for your help. I tried to check out the example code from CVS,
but I could not find it. Please give me some hint. Thanks.

Hi, Mickael:
Thanks for your warm-hearted and timely help.
I have tried this example with my own metamoel and models. It seems work
fine but the output model is always empty; when extracted to xml file,
it reports null-pointer exception. The metamodels, input model and
tranformation file are very simple and surely correct (I have run this
transformation successfully in an ATL project). I consider that this may
be due to wrong library. Would you please tell me what library I should
use and what version they are.
Thanks.
Michael.

Dependencies and versions are explicitly set in the META-INF/MANIFEST.MF.
The NPE may be related to wrong resources path or something like that,
try running this code in debug mode, and you'll hopefully get more
details...
