You cannot call methods of JSP or Serlvets from outside.
A calling servlet or jsp is one that forwards itself to
another jsp or serlvet and does not return.
A Servlet or JSP loads once and thereafter is loaded, until changed again.
Once loaded, a calling jsp or serlvet will not cause it to reload. It is
like a mini server -- running or waiting always.
To pass String values in a forwarding process do this:
request.setAttribute("SomeNum", "1234567");
then:
<jsp:forward page="MyRelativeURL.jsp"/>
And in the called JSP:
<%
int Num = Integer.parseInt(request.getAttribute("SomeNum"));
%>
