Java EE has the concept of an ServletContext, which is an interface for communicating with the container that is running a Java EE application.

The Spring framework has an ApplicationContext class which is a way of communicating with the Spring container. In other words, it's a high level way of communicating with the Spring framework.

An HttpSession is state maintained by an application server for a series of requests made by a client. The HTTP protocol itself is stateless, so this is a way to keep some data about the user's interactions around.
