J2EE Connector Architecture(JCA) - An Introduction

JCA, the J2EE Connector Architecture, is an initiative towards EAI, Enterprise Application Integration. It is a standardized architecture providing the J2EE Components to have plug and play access to heterogeneous EIS, Enterprise Information Systems. Examples of EIS are ERP (Enterprise Resource Planning), Transaction Processing Systems, Legacy Database Systems etc. 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 Persistence API(JPA)

Java Persistence API (JPA) provides POJO (Plain Old Java Object) standard and object relational mapping (OR mapping) for data persistence among applications. Persistence, which deals with storing and retrieving of application data, can now be programmed with Java Persistence API starting from EJB 3.0 as a result of JSR 220. This API has borrowed many of the concepts and standards from leading persistence frameworks like Toplink (from Oracle) and Hibernate (from JBoss). One of the great benefits of JPA is that it is an independent API and can nicely integrate with J2EE as well as J2SE applications.More>>
