NoClassDefFoundError in GroupLayout on browsing applet.

[nhutc]

I have a simple swing applet in NB5.5 preview included in a web application. On deploying to Jboss and browsing in IE6, The applet will not display. The Java console contains the following:

java.lang.NoClassDefFoundError: org/jdesktop/layout/GroupLayout$Group

Can anyone advise on the cause and maybe suggest a fix please. Thanks.

You need to make sure that file swing-layout-1.0.jar (in the IDE it is included in directory platform6/modules/ext) is packaged in the war file and available on the classpath of the applet. Hope it helps, please speak up if it did not.
