Response to: and escaping

I will add to your helpful comment:
Using Tomcat 5.x, include the following code in a JSP:
<c:set var="myValue" value="a tag </tag>" />
<c:out value="${myValue}" /></ br>

This will produce the following browser output in the client:

a tag </tag></ br>
a tag </tag>

Meaning that the client browser will output "</tag>" when the c:out element is used (because the "</ >" characters are escaped); however, including the EL statement in template text will cause the tag to be added to the underlying template code.

    Let me edit that message above because it did not display properly; here's the browser output of the two statements when select "View Source" in the browser:

    a tag </tag></ br>
    a tag </tag>
