java代码怎么写的？
成功执行后页面跳转到哪？
配置文件的Action中没有配置forward属性
代码 就是一个登陆界面如果用户名密码都是ABC 就跳转到JSP1 反而就跳转JSP2
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
MyForm myForm = (MyForm) form;
if(myForm.getName().equals("ABC") && myForm.getPwd().equals("ABC"))
{
return mapping.findForward("1");// TODO Auto-generated method stub
}
else
{
return mapping.findForward("2");
}
}
web.xml呢？
在这呢
<?xml version="1.0" encoding="UTF-8"?>
Action的forward为什么要定义成global呢
定义在对应的Action中不好吗？还有哪有forward名用数字来定义的，编码规范就一点都不注意吗？
好好的改一下再测试一下吧
错误的意思应该就是在跳转时找不到相应的forward
没有异常了 跳到.do文件就不动了没找到JSP文件
每次提交页面都到
http://localhost:8000/WebRoot/my.do;jsessionid=FB9E2E98E169309B2F9384C3557A8E8C
就不动了
设个断点，调试一下
有没有进Action
没有页面跳转了,所以停在那不动了
↑返回目录
