Hi Ravi, Your struts-config defines a mapping between action classes and forms. When you submit a form it is posted to the ActionServlet. This uses the mapping to work out which ActionForm to use; it then uses reflection to call the setter methods on the ActionForm that map to the input fields on your submitted form. So if you have a an html:text field with a property of username the setUsername method is called and the value of the text field is passed in as the argument. Finally the populated form is passed to the Action class specified via the mapping in the struts-config.
