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
