A {@code Session} is a stateful data context associated with a single Subject (user, daemon process,etc) who interacts with a software system over a period of time.
A {@code Session} is intended to be managed by the business tier and accessible via othertiers without being tied to any given client technology. This is a
great benefit to Java systems, since until now, the only viable session mechanisms were the {@code javax.servlet.http.HttpSession} or Stateful Session EJB's, which many timesunnecessarily coupled applications to web or ejb technologies.
