Question

I’m writing a basic web service using jax-rs. I’m testing the application using the following JQuery. I can access the parameters fine using the GET parameters but when I use POST, it fails. I use the following JQuery to test both only switching “POST” to “GET”.

$.ajax({
    type: "POST",
    url: "http://localhost:8080/MyWebService/",
    data: 'text=this is text',
    dataType: 'jsonp',
    success: function(data){

        console.log(data);

    },
    error: function(){alert('failure');}
});

The java end looks like the following. Please keep in mind I am not having any issues with the get portion.

@GET
public Response getWork(@QueryParam("callback") String callbackName, @QueryParam("text") String searchText,
        @Context HttpServletResponse response, @Context HttpServletRequest request) throws JsonGenerationException,
        JsonMappingException, IOException {
            System.out.println(searchText);
    return work(callbackName, searchText, response, request);
}

@POST
public Response postWork(@FormParam("callback") String callbackName, @FormParam("text") String searchText,
        @Context HttpServletResponse response, @Context HttpServletRequest request) throws JsonGenerationException,
        JsonMappingException, IOException {
    System.out.println(searchText);
    return work(callbackName, searchText, response, request);
}

When using GET, it prints the text but when using POST, it prints null. What is needed to be able to access the parameters using the POST method?

Answer 1

If you send form data, you should assign what type of content server will consume. So you should annotate POST method with @Consumes(MediaType.APPLICATION_FORM_URLENCODED). In other words, POST method should be something like this:

@POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
