Oh the JSP Spec has become a close friend of mine recently... I've read it
but I guess I don't understand what exactly is meant by dynamic vs. static
content and when you would use which. I mean I do know what static is but it
seems like I want to use the directive and just have the contents of the
file included in place.
The issue that brought me to question using the directive was that when I
make changes to the database, I need to touch the .jsp page that is doing
the including to get the changes to reflect. I'm beginning to suspect that
include is working exactly as it should and I have another problem...
