Tomcat
Meta-discussion of the purpose of this Wiki page
Integrating with Tomcat probably shouldn't be an Integration DG concern – this is Core Sakai. For instance, discussion of using Tomcat session replication and load balancing with Sakai is something affecting standalone Sakai deployments.
So, this doesn't count, and we should find a better place for it.
Meanwhile, there seems to be a lot of useful content whizzing by on the email lists with perhaps not as much collection and digestion of this content into Wiki format as would be ideal. So, for the moment, this page is a quick place to start collecting this links in a place that is Googleable and easily Linkable / Referencable.
