WebStart d/l servlet doesn't work in a war file but works wh
Hi,
I have made a Java WebStart download servlet based webapp archive due to its obvious advantages(http://java.sun.com/products/javawebstart/1.2/docs/downloadservletguide.html).
When I deploy the war file in tomcat it works perfectly fine. But when I deploy it in JBoss (w/ bundled Tomcat) it fails when I give a request for the JNLP file. Which is when the JNLPDownloadServlet tries to service the request.
Following is the stack trace I get on the JBoss console:

===========================================================
Now comes the strange part - When I exploded the war into a filename.war directory it works!!!
The reason I made the web start easy deployment war was to have the facility to distribute it without any hassles of configuration. Now I have to tell the users to explode in a directory with a .war postfix, etc.
Is there a way to tell JBoss to extract the war automatically the way Tomcat does? Or is there a solution to my above mentioned problem.
