To start, from which version did you upgrade? I ask because, when moving from ColdFusion 9 to ColdFusion 10 and 11, the ColdFusion Team changed the design of the session apparatus.
Thanks for your reply.
we upgraded from 11.0 to 11.3. So, no major change. We found issue within our packaging. cfusion.war web.xml was missing the servlet definition. It worked in our Linux environment after fixing web.xml. But on my windows machine, i'm still having issues with Upgrade.
It could be some other missing configuration.
First of all, is it recommended to transfer sessions they way you do, even though it worked? Have you checked the documentation on this?
In any case, the release notes for Updates 1, 2 and 3 of ColdFusion 11 apparently say nothing that is relevant to your problem. The following may or may not be relevant, but is worth looking into: (String)session.getAttribute(SessionConstants.USER_ID)!=null . What about using the CFML version of the code.
