Action class in Struts

[Java Tip]

HttpServletRequests are translated to business logic using Action class. HTTP request is processed by Action Class, corresponding HTTP response is created and ActionForward instance is returned.

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class LoginAction extends Action
{
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
...
}
}
