Expresso Project - Open Source 34 Members Online
Expresso now in the Jars top 5%!Web Application Development (AD) Framework.
Expresso is the most popular, powerful, enterprise-strength J2EE architectural persistence framework. Expresso extends Struts for developing database-driven web applications and builds on many other open source projects and open standards. Expresso is designed to shorten time-to-delivery of Web-based applications by providing a library of extensible Java Server components for providing services to web-based applications so the developer can concentrate on application logic. Expresso is based upon many years of collective experience from industry-leading software engineers, consultants, and enterprise Web developers; and its large userbase assured a tried and true solution.

Expresso integrates and builds on many open source projects including Ant, Bouncycastle, Cactus, Commons, Log4J, Maven, ORO, Oswego Concurrent, JUnit, Struts, Struts Validator, Tiles, Velocity, Xalan, Xerces, and more.

Expresso integrates with Struts which is a MVC light weight framework emphasizing presentation and application configuration; whereas Expresso adds capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance and JSP tag library etc.

Expresso enables developers to decrease their learning curve and time to solution, which translates directly into reduced costs and increased revenue for customers. For instructions to install/configure Expresso, download, then click the 'Documentation' link in left menu.

Development Version: 5.7
Direction: 5.6 is released and its 1000+ cvs commits includes Struts Validator Integration, Better Tiles support, Velocity support, Maven integration and Stored Procedure Support. Expresso 5.7 will have Struts 1.2.x integration. Expresso 6.0 will have additional componization - will have Expresso Core Edition and Expresso Standard Edition. The latter will include - making many of Expresso's existing services 'pluggable', i.e. so that another pool, such as Weblogic's, can be used instead. Everything is cached through pluggable Message Oriented Middleware making Expresso completely enterprise friendly. Enhancements to make all database transactions asynchronous. Please see the task list and/or Roadmap documents for details. Also see Expresso Enterprise project where you'll find new modules including Expresso WebServices integration, and additional facilities to ease scaling up to higher performance levels.
