Here is a scenario:
A user enters a query and submits it to servlet. The servlet prints "thanks
for the visit, ur query is being dealt with". At the same time the servlet
is accessing a database and searching for user's query. Then the servlet
updates itself with the information from the database.
My real question is that how can a servlet update itself. For example, how
would it know that it has retrieved data from the database.
Would I need to use respond.setHeader(....) method.
Thanks
Qasim
