Difference between Page and PageContext

Can someone please clarify the difference between Page and PageContext impilcit objects in jsp ?

page : page is of class java.lang.Object,and it refers to instance of generated servlet. // what does this mean ?

PageContext : pageContext is of type javax.servlet.jsp.PageContext.

Am not able to get the difference between these both, please assist.

Please be sure to ask JSP questions in the JSP forum. I have moved this post there for you.

JSPs are implemented by generating a servlet. The page variable refers to the servlet instance.

As your JSP should not have any Java code in it, this is no longer useful.

it means ...

with page ... you can work with the servlet

with pageContext you can work with the jsp

No. That is not the way to deal with "attributes" (scoped variables).

Then how do we use page in real ... ???

I mean we use it in our jsp page as <@ page ... >

what else ???

I've already pointed out that it is completely useless in modern JSP. In fact, it was pretty useless in ancient JSP as well. I never used it for anything.

thanks DEAR Mr. Bear

page & pageContext both are implicit objects in a JSP.
page is of type java.lang.Object & refers to the instance of servlet generated from 'this' JSP.
pageContext is of type javax.servlet.jsp.PageContext.
It does following:
1. provides methods to get & set attributes in different scopes.
2. provides methods to include or forward the current request to other active componets in the application
3. provides a mechanism to handle errorpage exceptionn processing.
4. provides mechanism to manage session usage by the page

As Bear suggested, there are better ways to deal with attributes in different scopes.
