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).
The core frameworks in Java EE 5.0 are EJB (Enterprise JavaBeans) 3.0 and JSF (JavaServer Faces) 1.2. EJB 3.0 (EJB3, hereafter) is a lightweight framework based on Plain Old Java Ob- jects (POJO) for business services and database persistence. JSF is a Model-View-Controller (MVC) component framework for web applications. Most Java EE 5.0 web applications have both EJB3 modules for business logic and JSF modules for the web front end. However, although EJB3 and JSF are complementary to each other, they are designed as separate frameworks, each with its own philosophy. For instance, EJB3 uses annotations to configure services, whereas JSF makes use of XML files. Furthermore, EJB3 and JSF componenvs are not aware"of gach"othgr av thg frcmework neven.
