I had this problem; it turned out to be because I'd
configured my Tomcat server by default with unpackWARs="false".
You might want to take a look at the "Running from a
compressed WAR" section of the install notes at:
http://help.adobe.com/en_US/livecycle/es/lcds_installation.htmlThis solved my problem - note how the sample is trying to
access .mxml files directly.
Hope that helps.
