Hi Paul,
I found the source of the problem. In my Ant build I use a Maven plugin to
get all my dependencies and then combine them in a single big jar.
I depend on two Jersey jars: jersey-core-1.0.3.jar and
jersey-server-1.0.3.jar. The problem is that they both contain a file:
METAINF/services/javax.ws.rs.ext.MessageBodyWriter. When combined, the file
from jersey-server-1.0.3.jar overwrites the one from jersey-core-1.0.3.jar.
That explains the "message body writer not found" error.
In the Jersey 1.0 version the server jar did not define the
javax.ws.rs.ext.MessageBodyWriter. That's why it was working properly.
I guess combining jar files was not the greatest idea...
Thanks for the prompt reply.
Gaetan
P.S. I like Jersey very much. Nice work!
