Hi jersey community,

The jersey 1.2 OSGi sample don't work in my equniox platform, because of
class loading problems, so I added a proxy class loader in the Activator
class and now it works fine.

Without the proxy class loader I got the follow exception:

java.lang.ClassNotFoundException: com.example.rest.JerseyApplication

Here (http://github.com/tux2323/jersey.sample.osgiservice) my fixed OSGi
Jersey Sample.
I also add my eclipse equinox target platform in the git project.

with best regards
