what is diffrence between Dynaactionform,actionform and
Dynavalidateform
Answer Posted / labourer in an mnc
ActionForm
This class must be subclassed in order to be instantiated.
Subclasses should provide property getter and setter
methods for all of the bean properties they wish to expose,
plus override any of the public or protected methods for
which they wish to provide modified functionality.
DynaActionForm
Specialized subclass of ActionForm that allows the creation
of form beans with dynamic sets of properties, without
requiring the developer to create a Java class for each
type of form bean.
DynaValidatorForm
This class extends DynaActionForm and provides basic field
validation based on an XML file. The key passed into the
validator is the action element's 'name' attribute from the
struts-config.xml which should match the form element's
name attribute in the validation.xml.
Differences
ActionForm does not create getters and setters like we
cannot write <form-bean name="loginForm"
type="org.apache.struts.action.ActionForm"> in struts-
config.xml.
DynaActionForm cannot be used if we want validation in that
case DynaValidatorForm can be used.
