Hi,
What is the difference between

getParameterNames() and
Are they both same or different?

No , they are not the same
getAttributeNames return a list of available attributes in the servlet context
getParameterNames return a list of all the parameters (the one in past in the URL) to the servlet
for more details, refer to the J2EE documentaion.
and search for the two methods above.

Hi Maitham,
I don't think attributes available through HttpServletRequest has anythig to do with servlet context. What i observed is that setAttribute() and getAttribute() available in HttpServletRequest is a way of passing objects via. a request while dispatching/forwarding the request to other servlets or web components. I guess with this functionality we can reduce the burdon on session by not overloading them with lots of objects. Correct me if i am wrong!
