Trying to run a swing application. I need to include jar file\nC:\java\lnfdir\newlnf.jar\non my class path. Easy to do if I knew where it was. I'm using Java\n1.6 and have searched for the jar file in all the directories under not\nonly Mustang but also the other Java versions I have. The error only\nhappens when I try to use the GTK+ look-and-feel.\n\nCouldn't find class for specified look and\nfeel:com.sun.java.swing.plaf.gtk.\nDid you include the L&F library in the class path?\nUsing the default look and feel.\n\nBased on a google search I did find this site\n[URL]http://www.codecomments.com/archive250-2005-5-388704.html[/URL]\n\nIs what they are saying accurate in the the GTK L&F is only available\nunder Linux?
