[jetty-users] Enable multipart support in Handlers under Embedded jetty

[Neil Williams <neil@xxxxxxxxxxx>]

Under Jetty 8.1.8 you have to explicitly enable Multipart support using a flag in the web.xml or using the @Multipartconfig annotation.

I have a project that uses embedded Jetty with no xml configs and with no WebAppContext, it is simply a few handlers directly added to the server (simplified example below).

After looking at this (https://bugs.eclipse.org/bugs/show_bug.cgi?id=395000#c0) bug report, the solutions offered to get annotations working to enable multipart support do not seem applicable to Handlers (or, at least setting the "org.eclipse.jetty.webapp.configuration" attributes on the server instance have no effect)

Is it possible to enable servlet 3.0 multipart support for handlers with this setup?

Thanks,

Neil

package anno;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.annotation.MultipartConfig;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.Part;

import org.eclipse.jetty.server.Request;

import org.eclipse.jetty.server.Server;

import org.eclipse.jetty.server.handler.ContextHandler;

import org.eclipse.jetty.util.log.Log;

public class AnnoTest {

  public static void main(String[] args) throws Exception {

    Log.getRootLogger().setDebugEnabled(true);

    Server server = new Server(9000);

    // String[] configuration = new String[] {

    // "org.eclipse.jetty.webapp.WebInfConfiguration",

    // "org.eclipse.jetty.webapp.WebXmlConfiguration",

    // "org.eclipse.jetty.webapp.MetaInfConfiguration",

    // "org.eclipse.jetty.webapp.FragmentConfiguration",

    // "org.eclipse.jetty.plus.webapp.EnvConfiguration",

    // "org.eclipse.jetty.plus.webapp.PlusConfiguration",

    // "org.eclipse.jetty.annotations.AnnotationConfiguration",

    // "org.eclipse.jetty.webapp.JettyWebXmlConfiguration" };

    // server.setAttribute("org.eclipse.jetty.webapp.configuration", configuration);

    server.setHandler(new PostHandler());

    server.start();

    server.join();

  }

  @MultipartConfig

  public static class PostHandler extends ContextHandler {

    public PostHandler() {

      super("/post");

    }

    @Override

    public void doHandle(String target, Request baseRequest, HttpServletRequest request,

        HttpServletResponse response) throws IOException, ServletException {

      System.out.print(request.getContentType());

      Part p = request.getPart("content");

      System.out.print(p.getSize());

      baseRequest.setHandled(true);

    }

  }

}

Calls to /post/ will result in the following:

java.lang.IllegalStateException: No multipart config for servlet
