Thanks for the suggestion, John, but it didn't work. I did a clean and 
rebuild of the project, then ran my Ant script to compile the code, jar 
it, and send the jar to the server but I'm still getting the same error 
in the same place when I execute the applet on a web page. The applet 
continues to run just fine in Eclipse, both as an applet and an 
application.

I did some googling looking for other reports of this error and found a 
suggestion to put a try/catch around the problem code so I did that:

        try {
        switch(FooConstants.DESIRED_FORMAT) {
        case PARAGRAPH_FORMAT:
            dataPanel.add(createScrollableBorderedTextAreaForParagraph
(this.doc.getDescriptionParagraph(entryNumber), 
this.doc.getDescriptionText()));
            break;
        case LIST_FORMAT:
            dataPanel.add(createScrollableBorderedTextAreaForList
(this.doc.getDescriptionSentences(entryNumber), 
this.doc.getDescriptionText(), LIST_BULLET_CENTER_DOT));
            break;
        }
        }
        catch (Throwable t) {
        	t.printStackTrace();
        }

Then I ran the Ant script again. The behaviour changed fairly 
dramatically after this change. When I try to run the applet in Firefox 
7, I get:

 java.lang.NoClassDefFoundError: Could not initialize class 
com.foo.FooConstants
 
The applet will not display. However, when I do the same thing in Opera 
11.52, the applet DOES display, although the console shows the same 
error. Ditto for Google Chrome: the applet displays but I get the error 
in the console. 

FooConstants is definitely in the jar - I have a little jarViewer class 
that I use to list the contents - so I'm not sure whether Java just isn't 
seeing it or is having some kind of problem initializing it.

I'm not sure what to try next because I don't really understand the 
underlying error.
