Hi Garann,
If you take a look at the generated Java Servlet code for your JSP it
should become clear why this doesn't work. The declaration is outside of
the service method of your JSP. Basically this means you can't use any
of the implicit objects directly as if you were writing a scriptlet.
To solve the problem you've got some choices. The easy but messy way
would be to make your methods take a HttpServletRequest object as a
parameter. So each time you call them, you'd pass in the request and use
it like you currently are trying.
EG:
<%! public String mkDate(HttpServletRequest) {
...
<%= mkDate(request) %>
A better solution would be to use a object such as a JavaBean or Custom
tag to abstract these methods. It would remove the spaghetti code
completely.
There are some good JSP links, articles, and tutorials on JSP Insider
(http://www.jspinsider.com). They will help you with this if you are
interested.
Cheers,
Jayson Falkner
