If it works fine in NetBeans, but the LAF does not appear, when running a jar file, it probably means that the LAF library wasn’t correctly discovered in the classpath. Since I don’t know your setup, I can’t really suggest the right answer. You could adjust your classpath settings when running the jar file (via jar -cp ...) or package your application as a single jar, with all the dependencies included – onejar is a convenient way to accomplish this.
