Hello list, I have two instances of Tomcat running the same webapp behind a load balancer. My current redeployment method is just simply shut one instance down(undeploy), replace warfile, deploy latest war back online, and then proceed to the seond instance.
This works most of the time, but for those users who are happens on the instances I shut down, they lost the session at best, and lost a form submission while middle of request at worst. Can you share your story of how you solve your redeployment problem to keep max availability of your webapp? Thanks, Zemian Deng
