the unique token.

com.opensymphony.webwork.util.TokenHelper.DEFAULT_TOKEN_NAME if no name is provided) so that the same token can be re-used for the scope of a request for the same name. If
the token is not in the PageContext, a new Token is created and set into the Session and the PageContext with
the name.
