clientside code is:

ClientRequest request = new ClientRequest(url);

Answer 1

Things that had made work my code were that I added:

    org.jboss.resteasy
    resteasy-jackson2-provider
    &{resteasy.version}

Beside this I don't know why but it seems that resteasy not initializing providers when client were created, this means that it required to init them manually:

 ResteasyProviderFactory instance=ResteasyProviderFactory.getInstance();
 RegisterBuiltin.register(instance);
 instance.registerProvider(ResteasyJackson2Provider.class);

In general it's enough to run the client.
