Hi,
@GET
@Produces("application/xml")
public WorkflowTaskResponse queryTasksByXml(
MultivaluedMap<String, String> params,
@DefaultValue("0") @QueryParam("page") int page) {
}
@GET
@Consumes("application/json")
@Produces("application/json")
public JSONObject queryTasksByJson(
JSONObject request,
@DefaultValue("0") @QueryParam("page") int page) throws
JSONException {
}
The above GET methods are in error because there is a method parameter
that is not annotated and Jersey assumes that those correspond to
request entities. Validation of the resource class is failing. GETs
should not really have entities associated with the request so Jersey
disallows it. The details should be in the logs should tell you why
validation fails.
If you want to get access to the all query parameters do the following:
@GET
@Produces("application/xml")
public WorkflowTaskResponse queryTasksByXml(
@Context UriInfo ui,
@DefaultValue("0") @QueryParam("page") int page) {
MultivaluedMap<String, String> params =
ui.getQueryParameters();
}
Paul.
