More verbose errors JavaFX applet

Hi all,

I'd like some help getting the java plugin to display some more verbose errors. I got a JavaFX applet to work, hosted from a webserver, just fine no errors. But as soon as I started using external jars in the applet I get a runtime error "JavaFX application could not launch due to system configuration" saying to click on a link to get more error details, but when I click on the link I see only this in the java console:

++Java Plug-in
++Using JRE version 1.7.0_10-b18 Java HotSpot(TM) 64-Bit Server VM++
++User home directory = /Users/jeroenbreedveld++
++c: clear console window++

++g: garbage collect++
++h: display this help message++
++l: dump classloader list++
++m: print memory usage++

++Match: endTraversal ..++
++Match: JVM args final:++
++Match: Running JREInfo Version match: ==
++Match: Running JVM args match: have:<> satisfy want:<>++

I believe that is exactly the same information that is shown when the applet runs fine, I see no error there?

Can anyone please tell me how to get more information on errors when running a JavaFx application as applet?

Thanks and regards,

    There should be a dialog that pops up when you have an error. For instance I sometimes have an error with "AbsoluteLayer.jar" which is a Netbeans library. It will give me a dialog that says okay or "details" If you hit details a Stack Trace should pop up... Same as if you clicked on "error." You also might not be doing something witht he external Jars at runtime, check your configurations.
