One of the easiest ways to pass an object around between servlets and Javaserver Pages is with a Session (javax.servlet.http.HttpSession)
Sessions are objects that are managed by the servlet engine and are identified by a unique "cookie" value. You can attach an arbitrary object to a session in one servlet with:
session.setAttribute("objname", theObj);
and get it back with
notherObj = (objtype)session.getAttribute("objname");
Use the HttpRequest method getSession() to get the
session associated with a request.
NOTE: the user's browser must be set to accept cookies.
