Question

我的申请有问题。我使用Java，JSP，Servlets，html等开发了一个应用程序。

突然我提交的所有按钮都不起作用。我昨天测试了我的应用程序，它工作得非常好！今天，当我想重新测试并进行一些更改时，所有提交按钮都不起作用。（我试图在IE，CHROME，FIREFOX中打开应用程序但它没有工作）。

.jsp页面

<body>
<form class="container">
<form id="search_form" class="form-horizontal" name="profile"    action="UserController" method="POST" accept-charset="utf-8">

    <%--<form class="container">--%>
        <h2>Employee Management <img src="http://seeklogo.com/images/S/salon-logo-F0E41E42DD-seeklogo.com.gif" style="float: right; height: 50px; width: 50px"></h2>

并且有2个解决方案 1.删除<form class="container"> 2.添加<form class="container" action="?" method="POST"></form>

表单中提交类型的HTML按钮不起作用
