Swagger got javax.ws.rs.client.ResponseProcessingException: No message body reader has been found for class>

I'm using swagger to generate my client code with JERSEY 2 Client lib. ( on server side - java-cxf )

I'm running my getUser() REST call successfully to my server and get back response code 200 with my returned USER Object Json representation.

But when try to convert the JSON into my USER Object (which is generated by swagger)

I'm getting

Steps to reproduce

This is snapshot of my Client.
try {

    User restUser = userServicesApi.getUser(authorization,testUser.getName());

} catch (Throwable e) {
    e.printStackTrace();
    Assert.fail(e.getMessage());

}

How should it be solved ?

There was an issue with the jersey2 lib for taxes and we've fixed it in the
latest master. Please pull the latest to give it a try.

Note: we also make jersey2 the default htto lib for jaxrs in the latest
master

@yuvalishay were you able to resolve your error? I just recently got started with swagger codegen and generated the javax rs cxf server code to be able to implement the interfaces myself.

1. All interfaces only return Response. Is that something to be expected?
2. When I try to convert the Response entry (application/json format) to its respective java class I get the same error as @yuvalishay (well not with User obviously but with the classes used)

[jfiala]

@yuvalishay @sthuber90 This should be fixed as of PR #4003, the CXF server stub generator now generates the proper @Consumes/@produces annotations, by default Json is provided.

[jfiala]

@wing328 I think we can close this as there has been no response?

[wing328]

Yup. closed due to no update.
