RE: What is the difference between ActionForm and DynaActionForm
In struts 1.0, action form is used to populate the html tags in jsp using struts custom tag.when the java code changes, the change in action class is needed. To avoid the chages in struts 1.1 dyna action form is introduced.This can be used to develop using xml.The dyna action form bloats up with the struts-config.xml based definetion.
RE: What is the difference between ActionForm and DynaActionForm
There is no need to write actionform class for the DynaActionForm and all the variables related to the actionform class will be specified in the struts-config.xml where as we have to create Actionform class with getter and setter methods which are to be populated from the form
RE: What is the difference between ActionForm and DynaActionForm
if the formbean is a subclass of ActionForm, we can provide reset(),validate(),setters(to hold the values),gettters whereas if the formbean is a subclass to DynaActionForm we need not provide setters,getters but in struts-config.xml we have to configure the properties in using .basically this simplifies coding
RE: What is the difference between ActionForm and DynaActionForm
An ActionForm represents an HTML form that the user interacts with over one or more pages. You will provide properties to hold the state of the form with getters and setters to access them. Maintaining a separate concrete ActionForm class for each form in your Struts application is time-consuming. It is particularly frustrating when all the ActionForm does is gather and validate simple properties that are passed along to a business JavaBean.
This bottleneck can be alleviated through the use of DynaActionForm classes. Instead of creating a new ActionForm subclass and new get/set methods for each of your bean's properties, you can list its properties, type, and defaults in the Struts configuration file.
RE: What is the difference between ActionForm and DynaActionForm
If you are using actionform then you should specify the getter and setter for each components of presentation (jsp ) in to FormBean file.So it is some what complecated one to specify each component for setter and header. To avaid this method we are having DynoActionForm.In struts-config.xml file we can specify the properties.

In case of the ActionForm user himself has to write the setters and getters when ever he adds a control. The same process is repeated again and again when user creates a view. DynaActionForm eliminates this burden and creates the form bean itself. This way we don't have to write setters and getters...infact we don't have to give any bean class. To use DynaAction Form, we have to declare the form bean as a DynaActionForm Type in struts-config.xml. You will have to declare the properties and their type too.

Dyna Action form is a Generic Action form which can be represent a form.The properties of the form bean can be represent at the time of Deploying the application.
Where as in the Action form the propeties are mentioned or tightly coupled to the form.
RE: What is the difference between ActionForm and Dyna...
Dyna Action is a Generic action form which represents a form.
properties of the form are decided at the timeof deplying the application.
Where as in Action form form field propertie are decided when we develop the application ,there is no chance if in future we want to change any modyfication without changing the entire application.
