ClassNotFound Exception in struts-example (b3)???

[Ritter, Steve]

Hello, I've got struts-b3 installed here and we were stepping through the 
struts-example.  A problem arises when I click on the "submit" button in logon.jsp -- 
I get a ClassNotFound exception:

[06/06/2001 16:12:39:511|17000] (ERROR) request_handler: Servlet Error: 
ClassNotFoundException: logon

I used the correct username password ("user", "pass") so I would have expected to get 
forwarded to mainMenu.jsp via the "success" foward mapping.  Any ideas what might be 
wrong?
