JAX-RS Client says returned a response status of 406 Not Acceptable but it working for JSON request - jersey

Question

Stack trace:
[java] Exception in thread "main" com.sun.jersey.api.client.UniformInterfaceException: GET http://localhost:8080/xxxxx/resourcesP/xml/ returned a response status of 406 Not Acceptable

Client code:
String response = resource.accept(MediaType.APPLICATION_XML).get(String.class); //
report("GET all in XML:\n", response);
Resource Code:
#GET
#Path("/xml")
#Produces({MediaType.APPLICATION_XML})
public Response getXml() {
checkContext();
return Response.ok(plist, "application/xml").build();
}
However, the json format is working but not XML and plain.
Is there any Jar file or some thing which I'm missing here? Please help.
