Tutorial: Understanding the New Features of JSP 2.0
Turning off the TLD Caching
The use of TLD
caching speeds performance at application startup and during JSP page translation.
However, you might typically turn it off under either of the following circumstances:
Your application does not use tag libraries.
or:
You have pretranslated the JSP pages and none of the TLD
files use <listener> elements for tag library event listeners. (See
"Tag
Library Event Listeners".)
