Deploying a RAP .war file in jetty - maven

Question

I created an hello-world RAP application following the eclipse tutorial. I have no problems starting it in eclipse.
Now i want to package it as a .war file with maven and deploy it inside a jetty server. That's the point where i'm already unsure if it is the right approach.
My .war file includes all RAP, equinox and maven plugins, a web.xml and a config.ini. I'm building it with Tycho but i'm open to other solutions.
config.ini:
#Product Runtime Configuration File
osgi.bundles=RapHello/BasicEntryPoint#start,\
org.eclipse.core.commands#start,\
org.eclipse.core.jobs#start,\
org.eclipse.equinox.common#start,\
org.eclipse.equinox.console#start,\
org.eclipse.equinox.ds#start,\
org.eclipse.equinox.http.registry#start,\
org.eclipse.equinox.servletbridge.extensionbundle,\
org.eclipse.equinox.http.servlet#start,\
org.eclipse.equinox.http.servletbridge#start,\
org.eclipse.equinox.registry#start,\
org.eclipse.equinox.servletbridge#start,\
org.eclipse.equinox.util#start,\
org.eclipse.osgi.services#start,\
org.eclipse.rap.jface#start,\
org.eclipse.rap.rwt#start,\
org.eclipse.rap.rwt.osgi#start,\
raphello.BasicEntryPoint#start
osgi.bundles.defaultStartLevel=4
web.xml (copied from another sample .war):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

</servlet-mapping>
</web-app>
When i deploy the file in my jetty server, i get no errors and it seems like the file gets picked up, but all i get are
HTTP ERROR 404
Problem accessing /hellorap. Reason:
ProxyServlet: /hellorap
i think i tried all possible paths. What i read so far is, that the path should be the file name of my .war but that doesn't work.
jetty start log:
INFO::main: Logging initialized #276ms to org.eclipse.jetty.util.log.StdErrLog

So the question is: What am i doing wrong? Is it even the right approach?
This answer doesn't seem to work so my error is propably at an earlier stage.
