在Tomcat Server 7.0.39上部署后，Web应用程序无法正常工作

Question

我们能够登录到应用程序，但无法加载Header.jsp

这是浏览器例外：

 org.apache.jasper.JasperException: An exception occurred processing JSP page /user/../layout/Header.jsp at line 36

33:     } 
34:   </style> 
35: <!--  <script type="text/javascript"> 
36:     var secondsBeforeExpire = ${pageContext.session.maxInactiveInterval};
37:     var timeToDecide = 15; // Give client 15 seconds to choose.
38:     var initialSessionTimeoutMessage = 'Your session is about to timeout in 5 minutes.Please save your work now!';

Stacktrace:
    org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:568)
    org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:470)
    org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390)
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:728)

Answer 1

它按预期工作。

<script type="text/javascript">
    var d = ${pageContext.session.maxInactiveInterval};
    alert (d);
</script>

您是否在下一行观察到以<!--开头的注释？ 为什么在<script标签之前使用<!-- ？

<!--  <script type="text/javascript">
