In your first servlet, where you gather the user information, the following
code
could be used (in your doGet()- or doPost()-method).
HttpSession session = request.getSession(true);
session.setAttribute("userid", new Integer(userID));
session.setAttribute("password", password);
getSession(true) indicates that a session for the user should be created if
it
doesn't exist; the following two lines add the user information to the
session
object. 'userID' is an int with the user's id, and 'password' (String)
his/her password.
Now, in your second servlet, do something like this to get the data.
HttpSession session = request.getSession(true);
int userID = ((Integer)session.getAttribute("userid")).intValue();
int password = (String)session.getAttribute("password");
For more information, just read the Servlet API documentation.
