ProcessingException: RESTEASY003215

[boldt]

Hello,

I deployed a JAX-RS service on my Wildfly 10, which worked out of the box. Now, I need to call another REST interface within my JAX-RS interface. I do it as follows:


ClientConfig config = new ClientConfig();
Client client = ClientBuilder.newClient(config);
Response res = client.target(url).request().post(Entity.entity("DATA", MediaType.TEXT_PLAIN));

Unfortunately, this throws an exception:

17:42:45,962 ERROR [stderr] (default task-1) Caused by: javax.ws.rs.ProcessingException: RESTEASY003215: could not find writer for content-type text/plain type: java.lang.String

Which dependency do I miss?

Finally, after one day of debugging: Removing the ClientConfig is the solution!

Client client = ClientBuilder.newClient();
Response res = client.target(url).request().post(Entity.entity("DATA", MediaType.TEXT_PLAIN));

Why is the ClientConfig forcing the issue?
