Jersey Response issue driving me batty!

[Manny Garcia]

Hi,

I'm using jersey 1.8 from the jersey bundle and running on glassfish 3.1. I'm writing a REST web service and all has been peachy, until I need to send a specific response code. Every time I try to get a ResponseBuilder object I get a very generic jersey exception. Here's my code:

1.     @GET
2.     @Path("/json/cid/{cid}/lang/{lang}")
3.     @Produces(MediaType.APPLICATION_JSON)
4.     public Response getCommunityMapJSON(@Context HttpHeaders headers,
5.       @PathParam(Constants.CID) Long cid, @PathParam(Constants.LANG) String lang) {
6.         MultivaluedMap<String, String> headerMap = headers.getRequestHeaders();
7.         String token = (String)headerMap.getFirst("token");
8.        
9.         JSONObject obj = null;
10.        try {
11.            MsessionService sessionService = MsessionService.getService();
12.            sessionService.validateSession(headers, token);
13.            // Save the session data (note this is different from saving the session in the db
14.            sessionService.saveSessionData(token, Constants.ACTION_GET_COMMUNITY_MAP_JSON);
15.
16.            obj = CommunityMapService.getPayloadJSON(token, cid, lang, null);
17.        } catch (ForbiddenException e) {
18.            LOG.error(e);
19.            obj = new JSONObject();
20.            ResponseBuilder builder = Response.status(403);
21.            builder = builder.entity((Object)obj);
22.            builder.header("Custom header", "custom value");
23.            Response resp = builder.build();
24.        } catch (UnauthorizedException e) {
25.            LOG.error(e);
26.        } catch (Exception e) {
27.            LOG.error(e);
28.        }
29.        
30.        return null;
31.    }

The method errors out on line 20. Note I know that this code doesn't do anything useful. I'm attempting to return a 403 response with a custom header. In my testing I deliberately call the method with parameters that will cause a ForbiddenException (a custom exception) to be thrown. Here is the error I see when I attempt to execute line 20 above:

SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container

Prior to this the method's return type was JSONObject and I wasn't attempting to modify the response in any way and life was hunky-dory. Does anyone have any ideas what I could do to make this work? I've been at it for hours.

Well, I found something that worked. I did not find any documentation that said to do it this way, but it has the virtue of working:

    @GET
    @Path("/json/cid/{cid}/lang/{lang}")
    @Produces(MediaType.APPLICATION_JSON)
    public JSONObject getCommunityMapJSON(@Context HttpHeaders headers, @Context HttpServletResponse response,
      @PathParam(Constants.CID) Long cid, @PathParam(Constants.LANG) String lang) throws IOException {
        MultivaluedMap<String, String> headerMap = headers.getRequestHeaders();
        String token = (String)headerMap.getFirst("token");
        
        JSONObject obj = null;
        try {
            MsessionService sessionService = MsessionService.getService();
            sessionService.validateSession(headers, token);
            // Save the session data (note this is different from saving the session in the db
            sessionService.saveSessionData(token, Constants.ACTION_GET_COMMUNITY_MAP_JSON);

            obj = CommunityMapService.getPayloadJSON(token, cid, lang, null);
        } catch (ForbiddenException e) {
            LOG.error(e);
            response.setHeader("merror", e.getMessage());
            response.sendError(Constants.FORBIDDEN);
        } 
        catch (UnauthorizedException e) {
            LOG.error(e);
            response.setHeader("merror", e.getMessage());
            response.sendError(Constants.UNAUTHORIZED);
        } catch (Exception e) {
            LOG.error(e);
            response.setHeader("merror", e.getMessage());
            response.sendError(Constants.SERVER_ERROR);
        } 
        
        return obj;
    }
