/WEB-INF/classes vs /WEB-INF/lib

Question

I\'d like to package my Java EE6 web classes (beans, filters, servlets) into jar and place it into /WEB-INF/lib/ directory along with other utility

Answer 1

I'd go for /WEB-INF/classes. It allows you to run your application in debug mode and hot-swap classes on change. If you package everything as a jar, you'd have to repackage and redeploy the app every time you change a class.
