Out of the box, the only support in the 2.0 API for this would be to use
sendRedirect(), which has performance impacts. You can pass beans in the user's
session (2.0 did not have request attributes, but they would not work across a
sendRedirect anyway so it is not a big deal).
Some JSP implementations based on 2.0 have implemented custom variations of the
old callPage() method from JSP 0.91 to get around this restriction. Check the
docs on your JSP implementation to be sure what is supported.
