PageContext and servletContext

I realize while developing tags that we use the PageContext to retrieve the ServletContext.
I also understand that is one servletcontext per "web application" per Java Virtual Machine,and that it is used by a servlet to communicate with its container.
But,what is the relevance and scope of PageContext?

But where exactly in the lifecycle of a session does the pageContext fit in - at what exact stage is it created,its utility and when is the current data inside it populated?

Page context is the "lowest" of the context scopes. Its lifetime is limited to a single JSP page.

Thanks.THen apart from retrieving the servletcontext,what are the other typical interactions a page will have or need to have with its pagecontext?I do not find much documentation on its interactions with JSP?

Take a look at the methods described in pageContext. API link
That is what it can do in a JSP page.

What I mainly use it for is to get/set attributes for the page.
 
I agree. Here's the link: http://aspose.com/file-tools
