Book excerpt: Practical Apache Struts 2 Web 2.0 Projects is nothing less than one of the first books to cover the agile, lightweight open source Apache Struts 2 Web Framework, an essentially new and improved Struts platform that should meet today’s more agile Java development needs. Apache Struts remains the most popular framework for building Java-driven web sites, despite continued challenges from competitive frameworks and APIs like JavaServer Faces (JSF), Wicket, Grails, and more. The new features incorporated into Struts 2 will help this powerful framework to maintain its top-ranking position for the foreseeable future.
