Maybe a misunderstanding from me but I tought Tomcat will keep session
info on each connection for a given time (let say 15 minutes). So if
1000 uses ask for a report in 15 minute it's 1000 session object. But
my numbers are too high anyway so probably this leak is not a problem ..
if leak exists :-)

Well, if you don't need the session just forget about it :-)
If you don't put anything into session and aren't using it in any
other way, why should there be a memory leak?

Thanks I was looking for doing the JSP <%@ page session="true" %>

I want to use Tomcat to hold a reportServer. It will receive request
from different users from different webApp to craft reports. It needs
to be sessionless, in fact since I don't need session I just wanted to
avoid a memory leak...

Re: How do disable session in tomcat 5.5?

Check the javadocs:
http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/http/HttpServletRequest.html#getSession()
Returns the current session associated with this request, or if the
request does not have a session, creates one.
If you don't want a session call getSession(false) or don't call the
method at all. As far as I know the webapp will be sessionless as long
as you don't call getSession() on request object and put
session="false" in all your jsps (otherwise in the generated java
servlet HttpSession session = request.getSession(); will be called).
Another question, what's your goal? Why do you need explicitely
sessionless servlets so badly? Isn't it sufficent just not to use the
session if you don't need it?

Leon

In fact I need to know How to have a sessionless Servlet? I search the
tomcat source and it seems I have nothing to do. But when I do a
request.getSession() I do receive a session object? Is that normal
behavior?
