pageContext.getParameter won't compile, because there's no such method
defined
In your code, <JavaComponents:calendar prevMonth="<%= prevMonth %>" />,
the second prevMonth should be a variable defined your jsp.
There should something like <% int prevMonth = request.getParameter
("prevMonth")%>
somewhere before that line.
The first prevMonth is an attribute of your custom tag. Don't confuse
yourself

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 :)
