loginaction.java

利用了Struts的MVC结构

package cn.com.ahead.A6;

import org.apache.struts.action.*;
import javax.servlet.http.*;

public class loginAction extends KrmAction {
  public ActionForward perform(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
    inilog();
    loginActionForm myaf=(loginActionForm)actionForm;
    String name=myaf.getUsername();
    String password=myaf.getPassword();

    System.out.println("user:"+name+" password:"+password);

   ActionErrors errors = new ActionErrors();
   Transaction ts = new Transaction("KRMA6");
   ts.setTSCODE("login");
   ts.setParameter("NAME", name.toString());
   ts.setParameter("PWD",password.toString());
    if(!(ts.commit())){
     errors.add("login_Message", new ActionError("login.error"));
     saveErrors(httpServletRequest, errors); //保存错误信息
     return (new ActionForward(actionMapping.getInput())); //如果有错误则返回   取自struts-config
   }else{
     return actionMapping.findForward("ok");
   }
  }
}
