Struts 1.1 and Validator Form

[Matt Raible]

I'm having some trouble using the Validator "Form" from commons in my
Struts app.  Does import org.apache.commons.validator.Form still extend
from ActionForm?

I'm getting the following error where "CourseForm" extends "Form".

java.lang.ClassCastException: com.onpoint.webapp.CourseForm
        at
org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:5
54)
        at
org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:606)

Thanks,

Matt
