Hi, ich versuche mit ein Eclipse mit Tomcat so zu konfigurieren, dass ich einen REST Service programmieren kann. Leider scheitere ich schon am Hello World 
Tomcat gibt mir einfach immer einen 404 Error.
Ich poste euch mal ein paar Infos, sind ja nur 2 relevante Files:

</servlet-mapping>
</web-app>
[/XML]
Ich dachte jetzt, dass ich durch http://localhost:8080/HelloWorld/rest/hello zumindest etwas anderes als 404 Error bekommen sollte.
Hat jemand einen Tip fuer mich?
