JaxRS Exception. Null URI Fragment.

jerviver21 May 7, 2013 2:31 PM

I have a problem. I'm trying to implement a REST full webservice with jersey:

@POST

@Consumes({"application/xml", "application/json"})

public Response createCustomer(Customer customer) {

Response respuesta;

try {

long customerId = persist(customer);

URI uri = URI.create("/" + customerId);

Response.ResponseBuilder builder = Response.created(uri);

respuesta = builder.build();

} catch (Exception e) {

e.printStackTrace();

throw new WebApplicationException(e,

Response.Status.INTERNAL_SERVER_ERROR);

}

System.out.println("Respuesta status: "+respuesta.getStatus());

URI locationUri = (URI)respuesta.getMetadata().getFirst(HttpHeaders.LOCATION);

System.out.println("Respuesta fragment: "+locationUri.getRawFragment());

return respuesta;

}

When I invoke the method throught a client, the service execute without any problem the method and the customer is persist, the response generate is OK with status 201. But after return throw an Exception and the response I got in my client is status 500.

I think that problem can be that fragment of the URI is null and for that reason throw a NullPointerException. What can i do?
