I have a map of values (form parameters) which vary. basically what I am saying is that the REST service should only care a bout a Map<String,Object> paramters.

I am doing a POST with one PathParam, and the rest are form parameters (count is variable).


I do the following at the client:

                      MultivaluedMap data = new StringKeyObjectValueIgnoreCaseMultivaluedMap();
                        for (Map.Entry<String,Serializable> param : inParams.entrySet()) {
                          data.add(param.getKey(), param.getValue());
                        }

                          WebResource res =
                                RESTUtils.prepareWebResource(nodeURL, EventConsts.URI_COMPONENT_EVENT, configProperties)
                                        .path(inEventGkey.toString());
                        ClientResponse resp = res.type(MediaType.APPLICATION_FORM_URLENCODED).accept(MediaType.APPLICATION_OCTET_STREAM_TYPE)
                                .header(EventConsts.URI_HEADER_USER_ID, inUserContext.getUserId())
                                .post(ClientResponse.class, data);


The URL generated is: http://10.40.4.99:8280/sandbox/rest/componentEvent/peer/28

My service does not seem to find the right combination of type/reader. This is the code:
@POST
    @Path("/peer/{eventGkey}")
    @Consumes("application/x-www-form-urlencoded")
    @Produces("application/octet-stream")
    public Response invokePeerActionWithParams(@PathParam("eventGkey") Long inEventGkey, MultivaluedMap<String, Object> inFormParams) {
...
}


Should I be using something different than the MultiValuedMap? Or else. The REST server tells me that it cannot find a reader for
type = javax.ws.rs.core.MultivaluedMap
FromProvider. isReadable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType) returns false.

I get this error:
A message body reader for Java class javax.ws.rs.core.MultivaluedMap, and Java type javax.ws.rs.core.MultivaluedMap<java.lang.String, java.lang.Object>, and MIME media type application/x-www-form-urlencoded was not found.
