Hi, Alex.
Since JSP's are turned into servlets before they are executed, I don't
see why you couldn't do this. For your convenience, JSP's have some common
objects already available for use. The "application" object is equivalent to
the javax.servlet.ServletContext object you would get by doing a
getServletContext() call. So, application.getInitParameter("key") should do
the trick, too.
HTH,

Hello TOMITA,
I know next to nothing about JSP. Haven't touched it. I use XMLC and
Barracuda to do presentation. However, I would think that you should
be able to use getServletContext() or something analogous in JSP.
