Javabeans are independent,reusable software modules they extend java's "write once",run any where and "reuse every where" capability.
Each bean has properties,events and methods associated with it.
The set/get methods are used for setting and getting the properties of a Bean.
For a short introduction on Javabeans you can visit
ActionForm: An ActionForm is a JavaBean that extends org.apache.struts.action.ActionForm. ActionForm maintains the session state for web application and the ActionForm object is automatically populated on the server side with data entered from a form on the client side.

Hi,
In Struts, java bean which extends ActionForm acts like a transform object between view (jsp) and action (servlet). so u can directly access the properties defined in jsp. on a return from servlet, it is useful in displaying the values of properties using BEAN or HTML tag of struts.
