Question

My problem is that I have a web form and I want to send this data to a Jersey restFULL Method.

in my Javascript I have this call:

 console.log('Sending event creation ---> '+eventInJsonString);
$.ajax({
    url: "/Bxip/rest/events/",
//  dataType: 'json',
    type: 'post',
    data: eventInJsonString,
    contentType: 'multipart/form-data',
    success: function(data) {
        console.log("success ", data.response);
    },
    error: function(data) {
        console.log("error ", data.error);
    }
});

My jersey method is:

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_HTML)
//Retornará HTTP_STATUS 204 (on success)
public String addEvent(
        @FormParam("title") String title,
        @FormParam("fechaInicio") String fechaInicio,
        @FormParam("lugar") String lugar,
        @FormParam("categoria") String categoria,
        @FormParam("description") String description,
        @FormParam("fechaFin") String fechaFin) throws IOException {

    System.out.println("ENTRAAA    = " + title + description);

And the result before sending the data:

 Sending event creation ---> {"title":"aaaa","description":"        aaaaa","fechaInicio":"bbbb","categoria":"Beber y comer","fechaFin":"forever"}

But in the Java server side the parameters are null:

ENTRAAA    = nullnull

How can I send @POST to this jersey method from the client?

Answer 1

Several ways to do this. Here you have two possibilities:

• Using from params

To receive @FormParam’s at Jersey you should send the data url encoded in the body of the post.

The ContentType of the request should be

application/x-www-form-urlencoded

and the content of eventInJsonString should be

title=aaaa&description=aaaaa&fechaInicio=bbbb&categoria=Beber y comer&fechaFin=forever

To process this in Jersey, you should change the @Consumes type to

@Consumes(MediaType.APPLICATION_FORM_URLENCODED)

This way you will get the @FormParam’s filled.

• Using json

The problem is that you are trying to send the data in json. If you want to send it that way, you need to change somethings too:

You need to change the request ContentType to

application/json

and in Jersey you need to change the @Consumes type to

@Consumes(MediaType.APPLICATION_JSON)

If you send it that way, you will also need to remove the @FormParam’s from the method:

public String addEvent(String jsonBody) throws IOException {

    // Now you need to parse the json to get your parameters...
