The document provides an overview of new features in JavaServer Faces (JSF) 2.0, including foundational changes, improved system events, resource handling, state saving, GET request support, and a more powerful component model with composite components and behaviors. Key additions are support for Ajax, easier component development through templating with Facelets, and performance improvements through partial state saving.

59. Enhancing JSF 2.0 Components Ajax : Declarative Solution : <f:ajax /> <h:commandButton ...> <h:commandButton...> <f:ajax event=”action” /> <f:ajax /> </h:commandButton> </h:commandButton> Do exactly the same thing since “action” is the default event for commandButton components. <h:commandButton...> <f:ajax event=”mouseover”/> </h:commandButton> JavaScript events supported too.
60. Enhancing JSF 2.0 Components Ajax : Declarative Solution : <f:ajax /> Regions <f:ajax> <h:panelGrid> <h:inputText id=”text1”/> <h:commandButton id=”button1” /> </h:panelGrid> </f:ajax> Ajax applied to “text1” and “button1”. Ajax not applied to panelGrid : no default event associated with it.
Open Source from Sun allows a combined vision of the stack - Open Source provides the quality gained from thousands of developers reviewing and testing the quality of the product, the innovations which are determined by the community who builds what they need not what a vendor desires or has been driven by a few major customers, allows customers full transparency into the source code to determine extensions and how to leverage code to full use, and last , open source allows customers to pay at the point of their value of the product – at production time not at the intial stages of development. Closed source solutions are a drain on the enterprise by costing up front extensive license fees plus uncontrolled annual maintenance fees, tools which improve productivity are often complex and they plus extensions built by the vendor lead to planned lock in.
