Hello, What's the difference between making a class singleton and setting a class variable in the application context ? If I make a class singleton , is it available till the server is shutdown ? Thanks

Application context is actually just "WAR-context" whereas singleton context is JVM wide(If your JAR is put in server's class path). Stuffs being stored in ServletContext will be unloaded, and reloaded when you reload the WAR, or updates the WAR. Singletons in the JVM will not be reloaded until you shutdown the server.
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
