The session object works similiar to a hashtable. It can contain any Java
object, although that is necessarily recommended. Remember not to forget to
cast from Object on retrievals.
// put it in the session
String thisString = rs.getString("FIRST_NAME");
HttpSession session = request.getSession(true); // create if null
session.setAttribute("FIRST_NAME", thisString);
//----------------------------------------------
// retrieve and remove from the session at a later stage
HttpSession session = request.getSession(); // don't create if null
String thatString = null;
if (session != null)
thatString = (String)session.getAttribute("FIRST_NAME"); // cast to
String
session.removeAttribute("FIRST_NAME");
else...
//----------------------------------------------

Subject: FW: JSP & Sessions & Recordsets
Hi Folks,
I have an exceedingly elementary question about JSP. I am trying to process
a login for a user, validating the data from the database and then setting
up
session variables.
I am a native ASP programmer, but thought I was making progress in JSP,
though
it seems not. My greatest hurdle at the moment is making a field from a
recordset
equal to a local variable (string). I can't seem to do it.
In ASP I would do something along the lines of: (post
declaration)...
thisString = rs("FIRST_NAME")
I understand the JSP equivalent to be:
String thisString = rs.getString("FIRST_NAME");
Then...my problems continue. I am not sure how to declare, write to or
retrieve
session variables. Any assistance would be great appreciated.
Cheers,
Kate McNamara
