title: How can I define a JAX-RS service that processes multi-part data in JEE?
body: <p>This is what I have so far:</p>
  
  <p><strong>This initializes my REST service</strong></p>
  
  <pre><code>package com.dothatapp.web.rest;
  
  import javax.servlet.annotation.MultipartConfig;
  import javax.ws.rs.ApplicationPath;
  import javax.ws.rs.core.Application;
  
  @ApplicationPath("/authed/rest")
  public class JaxRsActivator extends Application {
  }
  </code></pre>
  
  <p><strong>And this what my service looks like:</strong></p>
  
  <pre><code>import javax.servlet.http.HttpServletRequest;
  import javax.ws.rs.Consumes;
  import javax.ws.rs.POST;
  import javax.ws.rs.Path;
  import javax.ws.rs.Produces;
  import javax.ws.rs.core.Context;
  import javax.ws.rs.core.MediaType;
  import javax.ws.rs.core.UriInfo;
  
  import org.json.JSONObject;
  
  @Path("fileupload")
  public class FileUpload {
  
      @Context
      private UriInfo context;
  
      @POST
      @Consumes(MediaType.MULTIPART_FORM_DATA)
      @Produces(MediaType.APPLICATION_JSON)
      public JSONObject doUpload(@Context HttpServletRequest obj) {
          try {
              obj.getParts();
          } catch (Exception e) {
              e.printStackTrace();
          } 
          System.out.println(us);
          System.out.println(es);
          System.out.println(obj);
          return null;
      }
  }
  </code></pre>
  
  <p>I tried adding <code>@MultipartConfig</code> to <code>JaxRsActivator</code>, but I still get an Exception: <strong>Request.getParts is called without multipart configuration. Either add a @MultipartConfig to the servlet, or a multipart-config element to web.xml</strong>. </p>
