Event Driven Programming with JSF

Event Driven Programming with JSF

This article discusses theories and concepts related to JSF Event Model. It details the supporting high level classes and interfaces that are involved in JSF Event Handling Mechanism. The logical categorization of JSF Events is also explained along with code snippets. Then, the tags available in the core JSF Framework are also discussed.

Accessing Web Services from JSF applications

Accessing Web Services from JSF applications

In this technical article, let us see how it is possible to access Web Services from JSF Applications. JSF Application resides in the Web Tier of a typical Enterprise Application, whereas Web Services are External Services that reside in the Application Tier. We make use of Java EE 5 for developing the Sample Application in the final section of this article. It is assumed that readers have sufficient knowledge of JSF and Web Services before continuing this article.

Using JSF and AJAX with Ajax enabled JSF implementations - Ajax4Jsf

With the advent of internet, there has been constant paradigm change from time and again. There are many scripting web languages which came and showed their impact now and then. But the feature I am going to talk about will give a close look to internet as a close friend. In this article, read full article

Introduction to Ajax4Jsf

Java Server Faces provided a Component Based Architecture for building User Interface Components for the Web Application. Ajax aims in providing Faster Response to the Client Applications by reloading only the needed Data. Wouldn't be nice to take the advantages of both Jsf and Ajax for developing Robust Web Applications. Ajax4Jsf provides solution for this. It is the integration of Java Server Faces with Ajax (which stands for Asynchronous JavaScript and Xml), thereby providing Ajax Support to the Jsf UI Components. This article attempts to provide an overview of the Ajax4Jsf Framework which is now an open Source Project in the JBoss Community. read full article

Unified Expression Language in Java Server Faces(JSF)

One of these is the UI component framework, JavaServer Faces technology. To support its powerful features, this framework needed its own expression language (EL). However, this EL presented some problems when used with some JSP tags. Therefore, the specification writers and expert groups of the Java webtier technologies collaborated on a new, unified expression language to help align these technologies by adopting the features offered by the JavaServer Faces expression language. These features include the ability to use expressions to set the value of external object properties as well as get data from them and to invoke methods. At the same time, the webtier team made the language pluggable and extensible so that advanced developers can add custom resolvers able to evaluate expressions not already supported by the expression language.read full article

Introduction to Java Server Faces(JSF) Core Tags Library

This article introduces about the various Core Tags that are available in JSF. Tags represent some set of Actions that will be executed in the Server. This article assumes the reader to have a fair bit of knowlege in Java Server Faces. If not, then they can visit the Introductory Article in JSF in javabeat. For more information and resources about Java Server Faces, readers can also Jsf Articles Page visit here. This article will start off with the Major Classification of Core JSF Tags and then will explain in depth about the various different types of Tags that are available in each category. Wherever and whenever possible, Code Snippets are given to make the understanding of the Tags much clearer.read full article

Introduction to Java Server Faces

Java Server Faces (JSF) simplifies the development of User Interfaces in a typical Web application. It provides a Component-based Pluggable Architecture for developing and representing User Interface Components. Also bundled with JSF is a whole set of various new features like Event Handling Mechanism, Page Navigation, Input Validation and Conversion. This article provides an overview about JSF Framework and the various core elements that form the basis for a JSF Framework. It then provides a detailed overview about the various phases in the JSF Request Processing Life-cycle. Explained further is the structure of the JSF Configuration File. And finally the article is concluded by providing a sample application that demonstrates the various new features.read full article
