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).

Gavin King, Seam creator, is also the Expert Group lead on JSR-299 (http://jcp.org/en/jsr/detail?id=299) which is based on many of the concepts that are part of Seam.
