JV013 - Web Development with SEAM

Summary

This 3 days course provides students with an introduction to Seam, a new application framework developed by JBoss.  Seam integrates technologies such as AJAX, Java Server Faces (JSF), Enterprise Java Beans (EJB3) to simplify the development of next generation Web 2.0 applications. Seam unifies the component models of JSF and EJB3, eliminating glue code, and letting the developer think about the business problem.
