All three are javaBean Class that can maintain the session
state for web application. The ActionForm object is
automatically populated on the server side with data
entered from a form on the client side.
An ActionForm/DynaValidateForm can have getter(),Setter(),
reset() and the validate() methods that can be defined in
your actionForm or in Action class itself. If any changes
are made to the properties, code need to be recompiled.

Her comes the DynaActionForm to rescue. It allows
properites to be specified in Struts-cofig.xml file there
by avoiding the recompilation of the code.Also there is no
need to have a Form Bean for every page that had getter and
setter method for each of the field on the page.

This is how it can be declared in struts config file:
<form-beans>
<form-bean name="employeeForm"
type="org.apache.struts.action.DynaActionForm">
<form-property name="fname" type="java.lang.String"/>
</form-bean>
</form-beans>
