Very simple. Store the result set in a bean with session scope. Then, all
pages accessed by the same one user during the same one session (most
servlet engines default 30 minutes of inactivity for a session before
expiring it) can access this list. If your not familiar with "scope", its
handy to know. There are basically 3 scopes with beans. Request, Session and
Application. Request means the object exist for the duration of the request
on the server (including forwarding to a JSP page..so you can have a servlet
put an object in the request passed in, then forward to a JSP page that also
has access to this same object. The engine then discards that object once
the response goes back to the client). Session exists the entire time the
user is using your site while their session is still kept alive. All pages
they access can access this one object (or any object stored in the
session). Application scope is dangerous but sometimes useful. Its a GLOBAL
scope that all sessions can use. Therefore its not thread-safe. It is useful
for lookup objects, or routines that are used by many pages for many
sessions at the same time. But remember, do not put any methods in an object
that can be "written" to at the same time without first syncronizing the
method(s).
So to store something for the next page to access, you do something like:
request.getSession(true).setAttribute("AttributeName", object);
On the following page, you will have to typecast the object to the right
type:
MyObject myObject = (MyObject)
request.getSession(true).getAttribute("AttributeName");
If this hasn't helped, elaborate a bit more and I'll see what I can do.
