Hi to All 
Could you please explain to me what these two methods pushBody() & popBody() of PageContext do.
I am reading the API over and over but cannot figure out what they want to say.
The rest of the methods are pretty clear.
Thanks!

Is this a particular implementation that you are looking at?
Where did you find: "PageContext do"?.

I don't get your question but look,
If you read what the API says in the two links I have mentioned above, there is an explanation there regarding what those methods do.
I don't understand that explanation.
public BodyContent pushBody() Return a new BodyContent object (BodyContent of what?), save the current "out" JspWriter (save where?), and update ( update with what data?) the value of the "out" attribute in the page scope attribute namespace of the PageContext (Hold on, this API does not mention earlier that the page scope of this PageContext has a "out" attribute. I thought the PageContext just has that attribute with no specific scope.) What is this all process good for?

1) BodyContent of your JSP
2) I think your content will saved in some temprary loction before updating the jsp view
3) PageContext has most of the objects you need in taglib including the out object
