Hi Yann, I'm running an older version of Jersey on app engine (1.3) which runs fine.
One tip that I can give you is not to use classpath scanning as you do now. Just create an Application and register that in your web xml (it's easier to debug too). That will give you better start up performance on App Engine. If you do use classpath scanning, I hope you understand that your resources should be in the package "net.whatever.rest" for Jersey to find them?
