Introduction to Spring Web Framework

Today, the Principle of Inversion of Control has gained much popularity and Spring is a Light-Weight Framework that adopts this principle extensively for Building Java or J2ee Applications.

These features include the ability to use expressions to set the value of external object properties as well as get data from them and to invoke methods. At the same time, the webtier team made the language pluggable and extensible so that advanced developers can add custom resolvers able to evaluate expressions not already supported by the expression language.read full article
