PageContext

i find in one book that "PageContext is container to all implicit objects and user defined objects.It Provides setters and getters to use these objects".But my dought is how it can provide getters and setters for user defined objects can any body explain me this sentence

PageContext is container to all implicit objects and user defined objects.It Provides setters and getters to use these objects...

I would venture to guess that this is bad editing and what the author meant was that the PageContext provides getters and setters to use the implicit objects/properties provided by the PageContext class. It can also mean that there is a getter/setter for the attribute property which is how the user defined object would be stored and retrieved, just like from the HttpServletRequest and HttpSession.

The proper term for instances of objects stored in the various scopes, including page scope, is scoped variables.

And I agree with Gregg -- the passage is worded badly.

Thank you
