What do you mean by writing you own method in the Action class??
The Action class is the class, which provided by Struts framework, that your action class should be derived from. And typically you need to override the execution() method of the Action class to provide your own business logic. In your own action class you can define any methods that you like just any Java class that you're typically write.
Here is an example of how to derive your own action class from the Struts's Action class:
public class MyAction extends Action
{
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) throws Exception
{
String forwardTo = "success";
if ( !perform_bussiness_logic() )
{
forwardTo = "failure";
}
return mapping.findForward( forwardTo );
}
private boolean perform_bussiness_logic()
{
boolean status = true;
// perform bussiness logic
// .....
return status;
}
}
Hope this help.

public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response )
this is fine my query is:
who creates the references for these?
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,

The ActionMapping and ActionForm objects are created by RequestProcessor object in the process() method. The HttpServletRequest and HttpServletResponse objects are passed in from ActionServlet object.
Btw, the RequestProcessor object is the one that actually call the execute() method that you own action class provides.
