While writing a page in JSP, we can either use the implicit variables
application,request,session
or use the pageContext variable along with pageContext.Application_SCOPE etc.
Why should we use pageContext in place of the implicit variables, and what are the advantages/disadvantages for using either of them.
ex:- Why use
pageContext.setAttribute("Key","Value",pageContext.REQUEST_SCOPE)
vs
request.setAtrribute("Key","Value")
Edit:
Nathan Hughes proposed that my question is a duplicate. But the question he , provided a link to elaborates pageContext with respect to ExpessionLanguage while my question actually relates to pageContext with respect to Scriptlets.
Expression Language - ${pageContext.session} - This returns a Session object.
Scriplets - <% pageContext.SESSION %> - This returns a String.
The pageContext variable has different behavior in the above two Contexts. So , now that i have established how my question differs, can anyone answer my original question?
