How to use a web form with JAX-RS

Question

I am new to JAX-RS and so far I have created a simple CRUD REST service for my model Entity which has some String and Float attributes.

Right now this is how I can create a new Entity:

@Path("/entities")
public class EntityController {
    @POST
    @Consumes({"application/json"})
    @Produces({"application/json"})
    public Entity createEntity(Entity entity) {
        if (EntityDAO.createEntity(entity) return entity,
        else return null;
    }
}

And this works just fine.

However, as I go forward into this API I would like to be able to make a simple form (in jsp I guess) to submit and create a new Entity.

I have seen some answers to similar problems here, here, here or here. However, as I am new to JAX-RS and web services actually, I cannot decipher what's going on.

I would like some help and I'd really appreciate if you could point out all the components that take part into the given solution in case I am missing an obvious step.

Just use @FormParam to inject form data:

@POST
@Consumes("application/x-www-form-urlencoded")
@Produces("...")
public Entity proceedForm(@FormParam("name") String name,
                          @FormParam("age") int age) {
    // ...
}

where should I store the html form in my project tree? I am guessing to access it from the browser I will have to set up some kind of resources in some xml file, right? – dabadaba Oct 16 '15 at 16:42
If you're using tomcat, place html or jsp file in `WebContent` folder – Alex Salauyou Oct 16 '15 at 16:53
Or you can create one more @GET method which @Produces("text/html") to return this page directly from service – Alex Salauyou Oct 16 '15 at 16:56
and how can I access the html file under `WebContent` from the browser? `localhost:8080/projectName/form.html` doesn't work. Do I need to set up anything else? – dabadaba Oct 18 '15 at 20:09
This is hard to answer without knowing your environment, servlet and jax-rs provider and so on – Alex Salauyou Oct 19 '15 at 07:26
what do you need to know? – dabadaba Oct 19 '15 at 09:44
