Java web application for teaching - now with sessions and clustering / load balancing demonstrations

• L - Linux, the operating system
• A - Apache - the Apache httpd web server that's commonly used to front web sites
• T - Tomcat - the Apache Tomcat (formerly Jakarta Tomcat) web server that provides the Java Servlet container
• M - MySQL - the database commonly used for data store and access
• J - Java - the programming language that's usually used to write substantial web apps.
Not only are these letters in this order a real "mouthful", but hosting may be on a Unix or Windows box, NginX may be used a the web server, Maria DB or SQLite may be the database and the Java source may have been replaced by Scala - yet the principles remain very much the same and our Deploying Apache / Tomcat course remains rather relevant until several elements are replaced.
So today I have copied (with no source code nor HTML changes needed!) latmjdemo.war to WellHouseApp.war, made a couple of minor revisions, and added further demonstrations into the application. These have been available as source code on our web site anyway - but they're now in the main distribution for the "tomcat course".
• Barman - a session tracking demo
• Landlord - sessions and application wide retained information
• PubWatch - sessions across multiple servers for clustering and load balance training
Both old and new web applcations are available for delegates (and others) to download from our servers -
