It can't work without <xsp:logic> or it works incorrectly. What kind of an error do you get? > I would like to know if the session attribute "valeur" must have been > declared before or not. It's not related to XSP or Cocoon. Attributes behave as they do usually in servlets, nothing different. So, if you have no "valeur" attribute in your session then you'll get 'null' string. > I search any good xsp tutorial and a downloadable api doc of cocoon. To understand XSP better see generated java source files. You'll find them somewhere in working directory of your servlet container (e.g. under /work/localhost/cocoon/ directory in Tomcat). -- Konstantin Piroumian [EMAIL PROTECTED] > > I thank you for any help > > Xavier > > > > --------------------------------------------------------------------- > Please check that your question has not already been answered > in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]> --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
