Unexpected Error while Launching Application

Hi, I'm new to Java and building a JNLP app. When I try to launch my app, it bails out with the following Exception:

java.lang.Exception

at com.sun.javaws.Launcher.continueLaunch(Unknown Source)

at com.sun.javaws.Launcher.handleApplicationDesc(Unknown Source)

at com.sun.javaws.Launcher.handleLaunchFile(Unknown Source)

at com.sun.javaws.Launcher.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Yes, I've seen the other posts on this topic and followed the advise, yet the error persists.

My JMLP file:

One quick follow up question - surely there's a way to get more detailed information on what's going wrong here. Any troubleshooting advice?
