NoClassDefFoundError: with GroupLayout

[Karl Green]

Hi,

I am not sure if this post should be in this forum, the applet forum, or the IDE forum so please bear with me. I’m trying to add some functionality via a JApplet to a legacy web app. The app is running jdk1.4 on Tomcat5.5. I have developed the applet in Neatbeans6.5 and it runs fine as a standalone applet. I’ve added the applet to the legacy app and when I try to open the applet I receive the following error:

java.lang.NoClassDefFoundError: org/jdesktop/layout/GroupLayout$Group
I’ve search the online and learned that I needed to add the swing –layout-1.0.3.jar to my project libraries in NetBeans, which I have done. I have also added the following to build.xml for when I distribute the war file to production:

  <target name="-post-jar">
        <jar update="true" destfile="${dist.jar}">
            <zipfileset src="${libs.swing-layout.classpath}"/>
        </jar>
    </target>

I’ve restarted Tomcat and done a clean & build several times but I keep getting the same error. Any suggestions?

Thanks in advance,

Karl

Any suggestions?

Don't use GroupLayout.

That is why most people recommend you build the GUI on your own so you are not reliant on a specific IDE or its custom classes.
