今天用SSH做个例子,功能很简单,就是用户登录,什么都不添写,单击提交时候会显示ApplicationResources.properties资源文件写好的错误信息,但是现在JSP也面能出来,但提交时候出错:[size=small]HTTP Status 404 - Servlet action is not available[/size]
现在把程序代码公布下:

[b]问题补充：[/b]
刚按你说的测试了下,没有打印任何东西,之前我就知道是配置文件哪有错,但水平有限,看不出来啊!
麻烦高手在帮看看.谢谢~
[b]问题补充：[/b]
我按你们的办法都试了还是不行~~~~
呢？
你web.xml里不是对*.do做的过滤吗？html里form的action怎么没有.do?
你看一下struts-config.xml中的input="/form/login.jsp"是否正确。
[quote]
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
Student loginForm = (Student) form;// TODO Auto-generated method stub
[color=red]return null; [/color]
}
}
[/quote]
return null .没返回;
在该句
[color=red]return null; [/color]
之前
添加测试语句;
System.out.println("收到请求:"+form);
看看是否已经到了Action;如果未到这里,应该就是配置文件的问题了.
你看一下数据库的链接问题、

[/quote]
修改为
[code="java"]
[/code]
另外,确保你的 /form/login.jsp 存在.
晕？？？？你吧 改成不行？
