JBoss Seam Application Framework

JBoss Seam is a powerful new application framework for building
next generation Web 2.0 applications by unifying and integrating
technologies such as Asynchronous JavaScript and XML (AJAX), Java
Server Faces (JSF), Enterprise Java Beans (EJB3), Java Portlets and
Business Process Management (BPM).

Seam has been designed from the ground up to
eliminate complexity at the architecture and the API level. It enables
developers to assemble complex web applications with simple annotated
Plain Old Java Objects (POJOs), componentized UI widgets and very
little XML. The simplicity of Seam 1.0 will enable easy integration
with the JBoss Enterprise Service Bus (ESB) and Java Business
Integration (JBI) in the future.
