java.lang.NoClassDefFoundError

When I wrote a java application it using JFrame works fine. but I changed it to an applet (JApplet), I got error message in run time:
java.lang.NoClassDefFoundError: Project1$5
at Project1.showFieldCombo(Project1.java:331)
at Project1.ComboBoxShow(Project1.java:475)
at Project1.init(Project1.java:492)
at sun.applet.AppletPanel.run(AppletPanel.java:344)
at java.lang.Thread.run(Thread.java:484)
Process Exit...
I'm using a signed applet as a jar file and the jar file is in my classpath.

Thanks a lot,

Payam,

I am not able to figure out if u did define a .html file to make the applet run or if u had just changed the JFrame to JApplet and tried rerunning the same code using "javac" for compilation followed by "java" to run the applet.

U might want to "copy-paste" ur code in ur reply so that things get clearer.

Are you testing the JApplet in your browser or with the appletviewer. I don't believe most browsers support Swing. I think you need to install a plugin.

Thanks a lot for your replies,
I found the problem , I had used a jar file and some of my class file (with nnnn$#) weren't in the jar file.
Thanks again,
Payam
