我正在尝试在Tomcat 6.0中部署新的Web应用程序，但是每当我单击“开始”按钮时，我就反复

。每当我单击“开始”按钮时，其他已部署的应用程序运行良好。但是为什么不使用该应用程序呢？

 <web-app xmlns="http://java.sun.com/xml/ns/j2ee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
         version="2.4">
<servlet>
<servlet-name>j_security_check</servlet-name>
<servlet-class>EmailHander</servlet-class>
</servlet>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/fail_login.html</form-error-page>
</form-login-config>
</login-config>
<web-app>

web-xml文件中该错误的原因是什么？

回答：

您的web.xml结尾为<web-app>，但必须结尾为</web-app>

顺便 说 一下，这几乎 是 异常告诉您的内容。
