I am running a Debian Server with an installed Jboss 7.0.2 runnning on Java 1.7

After deploying the jenkins.war the Server is able to deploy and start the application. When I open the applications-url the jenins is displayed but there are no images shown.

The following exception can be found in the log after I opened the URL the first time:

It seems that the server is not able to find the deployed ressources. When I start it directly from the console (java -jar ..) the application starts.
Can you tell me where i have to search for the solution?
