I want to store some variables (e.g. number of rows per table) at page
scope in Spring framework so that each page has its own group of
variables. What is the proper way to do that with the spring 2.5.x
framework?

This has compile errors.
What is the proper way to initialize pageContext?
import javax.servlet.jsp.PageContext;

@Override
public ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {

PageContext pageContext;

Object o = pageContext.getAttribute("com.mycompany.pageId");

Description Resource Path Location Type
The local variable pageContext may not have been initialized
HwController.java /com.mycompany.monitoring.war/src/com/mycompany/
monitoring/war line 59 Java Problem

Are you sure you want page scope? Why not put it in the model, which
eventually ends up in request scope for JSPs views.

There is no page context in a Spring controller, because the Controller
is *not* a page.
