Also note that RESTEasy and Jersey cannot coexist ATM. Therefore, in order to use RESTEasy on GlassFish, you'll need to disable/remove the jersey bundle.
Jozef, replacing weld-osgi-bundle.jar did not work.
Unfortunately I cannot disable Jersey bundle on Glassfish as we have some web services in production that I´m not sure if they are using jersey proprietary API.
Also, seems like an overkill to have to do this, as I only want to use Resteasy client. Hope Resteasy guys in the future could separate the client API on a module that could work with any Rest implementation.
