The post i wrote some time ago about configuration of session replication in tomcat can be done in a much easier way now. Instead of setting up clustering of session objects via bootjars and heavy voodoo all we have to do now is configure a session replicating valve in your tomcat using application scoped meta-inf/context file!
EhCache is an API for caching in Java and its also integrated into grails by default. The only thing is that its not the latest version so if you want to use the latest terracotta and latest ehcache you will have to integrate it and set it up yourself. Its not really a big deal but i post this tutorial just hoping that it could help someone.
Terracotta is an amazing piece of software and it comes with some really cool tools and features. To enable Tomcat 6 session replication via terracotta you need to do a few things but its relatively simple lets do it.
