title: jax-rs retrieve form parameters
body: <p>I'm trying to retrieve some parameters that are passed to jax-rs from a posted form with the HttpServletRequest. However, my request object is always returning null values for my parameters. Am I not going about this the right way? I've posted the code below, along with an example request that is getting sent.</p>
  
  <p>Here is my service:</p>
  
  <pre><code>@Path("/")
  @Stateless
  public class HomeController {
  
      @Context
      private HttpServletRequest request;
      @Context
      private HttpServletResponse response;
      @EJB
      private LoginServiceLocal loginService;
  
      @POST
      @Path("/authenticate")
      @Consumes("application/x-www-form-urlencoded")
      public void authenticate() throws Exception {
          String email = request.getParameter("email");
          String password = request.getParameter("password");
          if (loginService.authenticate(email, password)) {
              response.sendRedirect("/app");
          } else {
              request.setAttribute("authenticationError", "Invalid email/password.");
  
          }
      }
  }
  </code></pre>
  
  <p>Example request:</p>
  
  <pre><code>POST http://localhost:8081/cheetah-web/authenticate HTTP/1.1
