[Resteasy-developers] Upgrading a client proxy from v2 to v3

[John U. <uj...@gm...>]

Hi all,

I'm upgrading an application from RESTeasy v2 (2.2.1.GA) to v3
(3.0.19.Final). In v2, I was using the client proxy framework like this:

public interface MyClient {
  ClientResponse<MyPojo> myMethod();
}

with a call pattern like this:

ClientResponse<MyPojo> r = client.myMethod();
checkSuccessful(r); //
MyPojo myPojo = r.getEntity();

With v3, things seem to be different.

The ClientResponse interface is deprecated, so I tried:

public interface MyClient {
  ClientResponse<MyPojo> myMethod0();
  MyPojo myMethod1();
  Response myMethod2();
}

Calling myMethod0 gives:

java.lang.ClassCastException:
org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine$1 cannot be
cast to org.jboss.resteasy.client.ClientResponse

Calling myMethod1 works and gives me a deserialized object, but it doesn't
give me access to the HTTP status code, which I need.

Calling myMethod2 gives a response object, but response.getEntity() is
always null.

I've probably got something wrong here, but I cannot figure it out and I
haven't found any more information in the documentation.

Thanks,

John
