How to configure implementation class in the deployment descriptor?

Question

i'm tring to add <listener> element to my web application. the web server is Apache plus Tomcat(3.2.3), and i add the following line to WEB.XML of Tomcat:
<listener>
<listener-class>
com.listeners.MySessionListener
</listener-class>
</listener>
<listener>
<listener-class>
com.listeners.ServletContextAttribListener
</listener-class>
</listener>
<listener>
<listener-class>
com.listeners.MySessionListener
</listener-class>
</listener>
(according to the direction of http://forum.java.sun.com/thread.jsp?forum=45&thread=150088. i have read the article in detail)
but nothing happened. when i make changes in the jsp page, nothing was noted in the the tomcat output window. i've got the MySessionListener.class and put it in the proper folder.
where should i add the <listener> element? can HttpSessionBindingListener or HttpSessionListener work without adding the elements to web application configuration?
thanks for your help and previous discussion!
best regards.

Hi
The Listener features are part of Servlet specification 2.3 which is supported by Tomcat 4.0 beta 7. Tomcat 3.2.3 supports Servlet specification 2.2.
To use listeners use Tomcat 4.0 beta version 7.
Good Luck!
