404是什么东西404呢？是运行项目404，还是提交后404，多么歧义。

<url-pattern>com.control/control_servlet</url-pattern>加个斜杠/com.control/control_servlet
<form name="view" action="com.control/control_servlet" method="post">最好这样
<form name="view" action="<%=path%>/com.control/control_servlet" method="post">
不这样的话你的action表示的是相对路径，一般用绝对路径好点
