The beanId local variable is just a copy of the session variable (see the
source code that's created for the useBean tag). It goes out of scope at
the end of the method and its value is NOT automatically copied back to
the session. You'd need to replace the session variable (using
session.setAttribute(...), for example) to accomplish what you want.
