| | | custom tag - param passing prob | custom tag - param passing prob 2007-03-08 - By Graeme McLaren

Hi there, prevMonth is defined in my extended BodyTagSupport class. I also
tried something like this within the JSP which didn't work:
<%!
int prevMonth = pageContext.getParameter("prevMonth");
int nextMonth = request.getParameter("nextMonth");
%>
Not really sure on this at all, any suggestions?
Thank you for your reply.
Graeme :)
