9. Comments and Character Quoting Conventions

There are a small number of special constructs you can use in various cases to insert comments or characters that would otherwise be treated specially. Here's a summary:

Syntax	Purpose
<%-- comment --%>	A JSP comment. Ignored by JSP-to-scriptlet translator. Any embedded JSP scripting elements, directives, or actions are ignored.
<!-- comment -->	An HTML comment. Passed through to resultant HTML. Any embedded JSP scripting elements, directives, or actions are executed normally.
<\%	Used in template text (static HTML) where you really want "<%".
%\>	Used in scripting elements where you really want "%>".
\'	A single quote in an attribute that uses single quotes. Remember, however, that you can use either single or double quotes, and the other type of quote will then be a regular character.
\"	A double quote in an attribute that uses double quotes. Remember, however, that you can use either single or double quotes, and the other type of quote will then be a regular character.
%\>	%> in an attribute.
<\%	<% in an attribute.
