Unformatted text preview: INTERNATIONAL INSTITUTE OF INFORMATION TECHNOLOGY P-14, Pune Infotech Park, Hinjawadi, Pune 411 057 Understanding J2EE Concepts In the first days session, you received an introduction to the new features available in WebLogic Server. After this you got an idea of how the book is organized and the structure of the sessions that you will be studying over the next few weeks. Before you proceed with the study of WebLogic Server, you need to be familiar with the technologies that make up the Java 2 Enterprise Edition. Today youll briefly cover the technologies supported by J2EE, such as Java Servlet API, JavaServer Pages, JSP tag libraries, Java Database Connectivity API, Java Naming and Directory Interface, Enterprise JavaBeans, Java Transaction API, Java Message Service API, and the J2EE Connector Architecture. This discussion will prepare you to study over the next few days how these technologies can be used in WebLogic Server. Finally, in todays lesson you will study the Model View Controller architecture and begin the design for your Airline Ticket Booking System, which will be based on this architecture. As this book presents each technology supported by WebLogic Server, you will build each of the parts of the Airline Ticket Booking System. Java 2 Enterprise Edition 1.3 Taking into consideration the disparate technologies based on the Java programming language and their application areas, the Java 2 Enterprise Edition ( J2EE ) is a move to combine the technologies under a common standardized architecture that lets developers leverage and mix- and-match the different technologies in Java. This makes more sense when building multi-tier enterprise applications that run on different operating systems and interact with different information sources. Multi-tier enterprise applications are inherently difficult to build, and without a standard architecture, that effort is repeated when building many enterprise applications. A standard architecture also demonstrates the validity of the concept that the different technologies will work together. Apart from the consolidation of different technologies under one roof, the J2EE specification also defines roles and demarcates responsibilities to be undertaken when an enterprise application is being built. Because these roles map to real-life activities that need to be undertaken, the J2EE specification has found acceptance in the industry. Moreover, the J2EE specification is an industry-driven effort to standardize enterprise application architectures and to reduce the time needed to build enterprise applications. Next you will study the different roles defined by the J2EE specification 1.3 supported by WebLogic Server 7.0....
