Thanks a lot to respond Konstantin,

What about the downloadable api doc, according to me, this doc and complexe examples, it's the best way to learn quickly ?

Subject: XSP Questions


hello,

I try to learn about Xsp, so I read the example.

I have this fragment

<xsp:page language="java" xmlns:xsp="http://apache.org/xsp">
    <comptes>
        <session>
            <xsp:logic>
                
org.apache.cocoon.environment.http.HttpSession session = 
(org.apache.cocoon.environment.http.HttpSession)request.getSession();
                String s = session.getAttribute("valeur");
            </xsp:logic>
            <xsp:expr>s</xsp:expr>
        </session>

An error occurs. When i erase the <xsp:logic> tag, it works.

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).
