问题 19. What is a Hidden Comment?

A comments that documents the JSP page but is not sent to the client. The JSP engine ignores a hidden comment, and does not process any code within hidden comment tags. A hidden comment is not sent to the client, either in the displayed JSP page or the HTML page source. The hidden comment is useful when you want to hide or "comment out" part of your JSP page.

You can use any characters in the body of the comment except the closing %> combination. If you need to use %> in your comment, you can escape it by typing %>.

JSP Syntax

<% comment %>

Examples

<%@ page %>

<html>

<head><title>A Hidden Comment </title></head>

<body>

<% This comment will not be visible to the colent in the page source %>

</body>

</html>

问题 20. How do I include static files within a JSP page?

Static resources should always be included using the JSP include directive. This way, the inclusion is performed just once during the translation phase. Do note that you should always supply a relative URL for the file attribute. Although you can also include static resources using the action, this is not advisable as the inclusion is then performed for each and every request.
