Re: [Resteasy-users] Replacing ProxyFactory with RestEasyWebTarget does not work
This is a Resteasy Client - JAX-RS 2.0 mismatch migration problem.
Replace:
response.getEntity()
with:
response.readEntity(String.class);
replace String.class to whatever class you want to marshal to.
getEntity() returns null if you haven't unmarshalled anything with
readEntity().

Re: [Resteasy-users] Replacing ProxyFactory with RestEasyWebTarget does not work
So, I've resolved my issue by updating my schema with jaxb:version=2.0
and regenerating
the jaxb classes. The tip off was Bill's mention of there being a
Resteasy Client - JAX-RS 2.0 mismatch migration problem
Cheers!
