Getting GTK error while running javaFX application on linux

Question

I developed an JavaFX application that works fine on Windows. So, I tried to run this same application on Linux (ubuntu x86) and it is not working. I setup all the environment with following this article : http://docs.oracle.com/javafx/2.0/release_notes_linux/jfxpub-release_notes_linux.htm. The Sample JavaFX applications available at http://www.oracle.com/technetwork/java/javafx/downloads/devpreview-1429449.html work great on Linux. But when I run my application, I got this error:
java -jar prototipoGui.jar
Exception in thread "main" java.lang.RuntimeException: Application launch error

I get the same message, when running my application in stand alone.
May be there is a problem when running in aa KDE environment.
But I developed my app in Eclipse under KDE4. If the app is started by IDE it runs.
