On a Linux workstation with Gnome as the windowing envrionment you will receive the following exception when running define or the client from the run script:

ERR  java.lang.NullPointerException
java.lang.NullPointerException
        at com.foundation.client.panels.FPanel.getName(FPanel.java:1324)
        at com.sun.java.swing.plaf.gtk.GTKStyle.getInsets(GTKStyle.java:274)
        at javax.swing.plaf.synth.SynthStyle.installDefaults(SynthStyle.java:896)
        at javax.swing.plaf.synth.SynthLookAndFeel.updateStyle(SynthLookAndFeel.java:275)

In order to be able to bring up the UI you will need override the default look and feel.  To do this edit the application’s properties file and add:

FClient.lookAndFeelClassName = javax.swing.plaf.metal.MetalLookAndFeel
