Problem with Java PS3 Media Server (swing library missing)

[Ben Edwards]

I have been trying to get the PS3 media server
(http://linux.softpedia.com/get/Utilities/PS3-Media-Server-43834.shtml)
and when I try to run it I get the following error (full log at end of
email):-

[main] TRACE 16:35:29.436 Class not found: javax/swing/GroupLayout$Group
Exception in thread "main" java.lang.NoClassDefFoundError: java/awt/SystemTray
	at net.pms.util.PMSUtil.addSystemTray(PMSUtil.java:39)
	at net.pms.newgui.LooksFrame.<init>(LooksFrame.java:242)
	at net.pms.PMS.init(PMS.java:280)
	at net.pms.PMS.get(PMS.java:895)
	at net.pms.PMS.main(PMS.java:957)

It seems to be saying it can not find a swing class;(.  I hove done a
bit of googeling and tryd to install packages that look theke they are
to do with swing but no luck  Any oideas?

Regards,
Ben
