First Release of Seam Plugin for NetBeans!

Petr Pisl of Sun has just released a first-look Seam Gen plugin for NetBeans. It allows you to generate complete Seam CRUD applications in NetBeans much the same way Red Hat Developer Studio allows you to do in Eclipse. I am extremely excited. So, here is a mini tutorial with some screen shots (taken from a Vista box — NetBeans look pretty good on Windows Vista).

Tutorial

1. Download and install the Seam module in NetBeans 5.5.1. We recommend you to install the Facelets support modules as well. Use “Tools -> Update Center -> Install Manually” to install those nbm files.

2. Install JBoss AS 4.0.5 with EJB3 support and set up a database with some existing data. Register the JBoss server and database connection in NetBeans. This is standard NetBeans stuff. If you are not familiar with that, read the Notes at the end of this post. You should see something like this in the Runtimes window after you are done. 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

Including Ajax Functionality in a Custom JavaServer Faces Component

Asynchronous JavaScript and XML (Ajax) is a technique for making the user interfaces (UI) of web applications more responsive and interactive. Because of its flexible and pluggable UI component model, JavaServer Faces technology is the perfect framework to use when adding Ajax functionality to your applications. With the DOJO JavaScript toolkit, it's even easier for component developers to add this functionality. This tutorial describes how to add the power of Ajax to JavaServer Faces components with some help from the DOJO toolkit.read full article

Ajax support in struts 2.0

Ajax or Asynchronous JavaScript and XML was introduced by Jesse James Garrett in 2005. He is called the “Father of Ajax” .Ajax is a collection of concepts and technologies that allows richer and more interactive user interaction with the web applications. The Ajax engine allows the user’s interaction with the application to happen asynchronously — independent of communication with the server. So the user is never staring at a blank browser window and an hourglass icon, waiting around for the server to do something.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
