RE: Exception creating bean: java.lang.ClassNotFoundException

[Anthony Martin]

I've had this happen too.  The classes compile, but fail to run.  It always
turns out to be some sort of CLASSPATH problem.  Check *.properties and make
sure any place you define classpath has the required classes there.  If you
use WinNT/2K, and Tomcat runs as a service, make sure you also check your
wrapper.properties that jk_nt_service.exe uses.

Subject: Exception creating bean: java.lang.ClassNotFoundException


Can anyone help me with this?

I have the classes in the right folders.  However, the ActionForm is not 
visible to the jsp page.
