In this article we will learn what are Enterprise JavaBeans ( EJBs ), what are it's different types and why to use EJBs in your application. EJB stands for "Enterprise JavaBeans" which are distributed network aware components for developing secure, scalable, transactional and multi-user components in a J2EE environment. Above definition actually describes EJBs from functional point of view i.e. what they do. A more structural definition would be : "EJBs are collection of Java classes, interfaces and XML files adhering to given rules".

JavaBeans are usual Java classes which adhere to certain coding conventions. Following are the coding conventions I am talking about : 1) Implements java.io.Serializable interface 2) Provides no argument constructor 3) Provides getter and setter methods for accessing it's properties

In this tutorial you will learn how to read XML files using Java. We will then apply this knowledge to create a Session bean ( EJB ) with ability to read given XML file and return a Java object containing values read from the XML file. So you will learn two things in this tutorial : 1) Reading and Parsing XML files using Java 2) Developing an XMLReaderEJB Session bean

In this article we will build a browser detection JavaBean which as the name suggests will try to detect your browser and display a useful message. You can use this bean as such or improve it to your liking. It is a very simple and light weight bean and should not take much memory on your server. You can use it on your site to detect user browser and render appropriate HTML to the user. Since different browsers don't support all the HTML and CSS features ( Netscape 4 being the main culprit ), this JavaBean can be of lot of help to you.

In this tutorial we will learn how to create our first Enterprise JavaBean. We will then deploy this EJB on a production class, open source, and free EJB Server; JBoss. JBoss is a really popular EJB Container and is used by quite a lot of organizations World wide. We will thus also learn how to install and run JBoss Server. The client for our EJB will be a JSP page running in a separate Tomcat Server.
