When a JSP page is compiled, the JSP code itself is turned into a servlet,
but the custom tags remain external to that servlet. The class files for
these must be a part of the web app for it to work.
Regardless, you do raise a good point. If things worked the way I had
supposed, then you would get into trouble very quickly if the text you
wrote to the body called for evaluation of tags that were not in your web app!
Obviously what the spec is referring to is not reevaluation of the body
text being generated, but of the code that was generated from the body of
the tag in the JSP. Duh! If I'd thought a little about how <logic:iterate>
works first... (Reminder to myself: turn on brain before answering questions!)
Thanks for setting me straight!
