Preface In just a few short years, Struts (now officially called Apache Struts) has grown from a simple idea hatched in Craig McClanahan's head into the most popular framework for building Java©-based web applications. There are other excellent Java-based web application frameworks available; many are newer than Struts, and most have benefited from lessons learned by the Struts users and developers. However, none of these frameworks offer the broad-range of features and functionality for which Struts is known. Just as important, the Struts communityone of the largest in the world of open source developmentactively supports fellow Struts users and drives Struts development. Thestruts-user mailing list often receives upwards of one hundred messages a day. Struts novices, experienced Struts users, and Struts committers are all active on this list.
