Corey,

thank you, it works fine, but I was not know that was create-session="true" exist.

Where I can find doc about all built-in taglibs and about their attributes?

Or better, do you know where I can search about it?

Very thanks?

Pier Paolo.

  hi,

  Have you setup a session using create-session=true or
  request.getSession(true)?
  for example

  1)
  <xsp:page
   language="java" create-session="true"
   xmlns:session="http://www.apache.org/1999/XSP/Session"
   xmlns:xsp="http://www.apache.org/1999/XSP/Core"
  >

  <Your stuff/>

  </xsp:page>

  Corey
