Hi Cyril, try adding xmlns:session="http://apache.org/xsp/session/2.0";
namespace to your xsp page. Then have a look at the generated code. Basically you should see a java variable (object) named "session", with it you can do what you want. No need to declare it, cocoon does it for you.

Isn't it really possible to add merely values to the same session's attribute with the ESQL logicsheet? It sounds odd...
