Web Application not working after deploying on Tomcat Server 7.0.39

Question

We are able to login into the application, but unable to load Header.jsp

Here is the browser exception:

 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

It works as expected.

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

Have you observed comment starting <!-- in below line? Why you used <!-- before <script tag?
