 In struts framework the ActionForm is generally define by the extending the org.apache.struts.action.ActionForm, Sometime ActionBean also called "form beans". These may be finely-grained objects, so that there is one bean for each form, or coarsely-grained so that one bean serves several forms, or even an entire application.

UsersDetailsAction.java

package com.r4r;

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 UsersDetailsAction extends Action
{
  String username;
  public ActionForward execute(ActionMapping mapping,ActionForm form,
  HttpServletRequest request,HttpServletResponse response) throws Exception{

    return mapping.findForward("success");
  }
  public String getUsername() {
  return username;
  }
  public void setUsername(String username) {
  this.username = username;
