How can I define a JAX-RS service that processes multi-part data in JEE?
This is what I have so far:
This initializes my REST service
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 {
}
And this what my service looks like:
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;
}
}
I tried adding @MultipartConfig to JaxRsActivator, but I still get an Exception: Request.getParts is called without multipart configuration. Either add a @MultipartConfig to the servlet, or a multipart-config element to web.xml.

Finally I managed to get this working by without Jersey coupling.
The problem is that @Multipart annotation doesn't work with the Application, so you need to define it inside web.xml and inside the Application class define the provided service. Inside the services you can use annotations normally. Also note, that I am extracting the Parts from the request, but this is very easy.
PS. This actually implements the back-end for bluimp JQuery file upload
web.xml
<servlet>
<servlet-name>com.web.rest.JaxRsActivator</servlet-name>
<multipart-config>
<location>c:\dotmp</location>

<max-request-size>218018841</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
