为什么JSP里的值传不到servlet里？

Question

检查web.xml中servlet的配置路径是否正确

Answer 1

web.xml文件配置出错，所以找不到这个Servlet的Location
请楼主把web.xml文件贴出来。到底对错就知道了。

Answer 2

不会把，也不会打出 E:\Shopping.......

Answer 3

Answer 4

<servlet>
    <servlet-name>loginservlet</servlet-name>
    <servlet-class>shopping.LoginServlet</servlet-class>
</servlet>这里给了调用LoginServlet类的别名，页面中调用只要用别名就可以了。不用在乎类在那个包下，是什么名称。

Answer 5

method="post"
^^^^^^^^^^^^^doGet(HttpServletRequest request, HttpServletResponse response)
^^^^^"post"=="get"???????

Answer 6

<form name="form1" method="post" action="LoginServlet">
你都method  post  怎么又在Get下面写啊...
