Chapt er 2 Chapter 2Programming for the Java 2 Platform, Enterprise Edition The Java™ 2 Platform, Enterprise Edition (J2EE™) is an architecture for a Java development platform for distributed enterprise applications. It was developed by Sun Microsystems, with input from the development community, including Borland. J2EE platform products, such as the Borland Enterprise Server, offer the developer the capability of building applications with these benefits: Reliability and scalability, so b

Through hard experience, however, the development community learned that building and maintaining a flexible distributed system is very difficult using the client-server model. For example, the business logic of the application was in the client application. Every time that logic needed modification, the revised application had to be installed on every c

Why are J2EE applications desirable? This expanded diagram shows you the various components you might find running on the various tiers: The client in a J2EE application can be a JavaServer Page (JSP), HTML page, or applet running in a browser; a Java application on a desktop machine; or even a Java client on some portable device, such as a personal digital assistant (PDA) or cell phone. The middle-tier can have a servlet or a JSP-generated servlet running on a web server. These elements us

Why are J2EE applications desirable? Benefits of the multi-tier model The multi-tier approach adopted by the J2EE platform has several benefits: It reduces the complexity of distributed development with a simplified architecture and the sharing of the work load among roles. The business logic of the application runs in the middle tier inside an Enterprise JavaBean (EJB) container and/or on a web server. These containers and servers can handle many of the difficult tasks for developers. For

How JBuilder can help How JBuilder can help JBuilder Enterprise Edition has many features to help your team develop J2EE applications. These are the technologies JBuilder has to help you develop the client tier: Client tier technologies Applets Applets are a special kind of Java application that are downloaded and run by a web browser on a client machine. To begin developing an applet in JBuilder, start with the Applet wizard. For information about working with applets, see “Working with

How JBuilder can help manipulate data from a database so you can build data-aware servlets and JSPs. For information about InternetBeans Express, see “Using InternetBeans Express” in the Developing Web Applications. This is the middle-tier J2EE technology that uses an EJB container: Enterprise JavaBeans (EJBs) Enterprise JavaBeans are server-side components that contain the business logic of the application. JBuilder assists you in building EJB 1.x and EJB 2.0 components. Start building en

Learning about J2EE Extensible Markup Language (XML) Although not really a J2EE technology, XML is widely used by J2EE technologies. For example, web components and enterprise beans have their deployment descriptors written in XML. These deployment descriptors describe how the components behave once they are deployed. JBuilder has several XML features that help you accomplish common programming tasks you might encounter in your J2EE projects. For information about JBuilder’s XML features,
