java - JSP not rendering properly in Tomcat

I have a JSP page running in Tomcat that is not rendering properly. Here is what helloworld.jsp looks like:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="cms-taglib" prefix="cms" %>
<html>
  <head>
    <title>${content.title}</title>
  </head>
  <body>
    <cms:mainBar
       dialog="my-page-properties-dialog"
       label="Page Properties"
       adminButtonVisible="true"/>
    <h1>${content.title}</h1>
    <p>Hello Magnolia World !</p>

    Current time: <%= new java.util.Date() %>
    <%-- JSP Comment --%>

  </body>
</html>

and the final output is like this:

<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib uri="cms-taglib" prefix="cms" %> Hello Magnolia World!

Hello Magnolia World ! Current time: <%= new java.util.Date() %> <%-- JSP Comment --%>

In short, it seems like only the expression ${content.title} is evaluated and rendered fine but everything else like the page directives, other JSP expressions and JSP comments are not.

I'm using a CMS that comes with Tomcat but the JSP templates samples from the distribution seem fine. I suppose it's something wrong from the code I written above.

Update: I've fixed the closed tag for the date expression and the comment. However, the page directives aren't being parsed.

I think there are problem with your jsp comment.

It should look like below. Are you not using IDE to develop your jsp? Your IDE should tell you when you have syntax error.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="cms-taglib" prefix="cms" %>
<html>
  <head>
    <title>${content.title}</title>
  </head>
  <body>
    <cms:mainBar
       dialog="my-page-properties-dialog"
       label="Page Properties"
       adminButtonVisible="true"/>
    <h1>${content.title}</h1>
    <p>Hello Magnolia World !</p>

    Current time: <%= new java.util.Date() %>
    <%-- JSP Comment --%>

  </body>
</html>
