Jersey Client API Exception Handling issue

[PankajKumar jaiswal]

Hi All,

I am trying to write a web service in Jersey, I am facing issue in exception handling at the client program.

Server Code snippet:

@POST
	@Path("/getEmp")
	@Consumes(MediaType.APPLICATION_XML)
	@Produces( MediaType.APPLICATION_XML )
	public Response getEmp(JAXBElement<EmpRequest> empRequest) throws EmpNotFoundException{
		EmpResponse empResponse = new EmpResponse();
		if(empRequest.getValue().getId()==1){
			empResponse.setId(empRequest.getValue().getId());
			empResponse.setName(empRequest.getValue().getName());
		}else{
			throw new EmpNotFoundException("Wrong ID");
		}
		return Response.ok(empResponse).build();
	}

Client code snippet:

public static void main(String[] args) {
		String uri = "http://localhost:8080/jd/rest/emp/getEmp";
		EmpRequest request = new EmpRequest();
		request.setId(2);
		request.setName("PK");
		Client client = Client.create();
		WebResource r=client.resource(uri);
		ClientResponse response = r.type(MediaType.APPLICATION_XML).post(ClientResponse.class,request );
		System.out.println(response.getStatus());
		if(response.getStatus() == 200){
			EmpResponse empResponse = response.getEntity(EmpResponse.class);
			System.out.println(empResponse.getId() + "::"+empResponse.getName());
		}else{
			EmpNotFoundException exc = response.getEntity(EmpNotFoundException.class);
			System.out.println(exc.getMessage());
		}
	}

I am getting following exception in statement "EmpNotFoundException exc = response.getEntity(EmpNotFoundException.class)":
500
