Hi Jeffery
Check what else they have open when they access your application. There could
be another J2EE application that does not scope it's session cookies correctly.
We have had ongoing problems with SAP portal servers scoping session cookies
across our whole domain, rather than scoping to the server they are running on.
When this happens, you get a session that does not belong to you. Ask them to
browse their cookies and tell you the scope (there are many Firefox plugins
that will make this easy).
Personally I think it is a shortcoming of the J2EE Servlet specification - all
session cookies are named JSESSIONID. This is not honoured by some IBM
products, but Tomcat adheres faithfully to the spec.
Regards
Ron
