be carefull to declare namespaces
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp"
xmlns:esql="http://apache.org/cocoon/SQL/v2"
xmlns:xsp-request="http://apache.org/xsp/request/2.0"
xmlns:xsp-cookie="http://apache.org/xsp/cookie/2.0">

this is an 2 years old implementation in XSP i have found in my disk
that
work

i'll suggest you to use flow instead of XSP (but this depends of your
needs)
