Overview of J2EE Development

Training Provided by Software Training Academy, Inc This course provides a coherent, high-level explanation of the Java 2 Platform, Enterprise Edition (J2EE): what sorts of software are created with J2EE; how software is developed for this platform; how it is deployed and put into production; how it can be administered. The course is designed specifically for non-programmers analysts, managers, technical writers, and anyone who desires a good conceptual understanding of J2EE while not needing to drill down into the details of particular APIs or runtime specifications. Developers may also find this course quite useful as a starting point for one or more of our courses in specific J2EE technology it gives a great sense of the big picture before one dives into the details of Servlets, JSP, EJB, or Java Web services. The course is presented seminar-style, with no hands-on exercises for students and no need for lab equipment. The instructor demonstrates several sample J2EE applications, including Web applications, EJBs, and Web services, and can go into source code and other details to suit the interests of the audience. But the focus is on architecture, and on boiling down a very complex system to its essential features: code portability, components and containers, declarative development. Students come to understand the roles that various J2EE technologies play in a multi-tier, enterprise application, and acquire the terminology and basic workings of each. Although the course treats J2EE at a high level, the instructor-operated demonstrations are fully-functioning Web applications, EJB applications, Web services, and so on. It is important that the presenter be well versed in J2EE implementation; that is, instructors for this course should be comfortable with teaching any of our other J2EE courses. LEARNING OBJECTIVES Understand the role of J2EE in the development of enterprise software in the Java language. Understand how J2EE facilitates integration of Java components with non-Java systems including relational databases, the World Wide Web, message queues, CORBA objects, and Web services. Appreciate the importance of the container/component architecture, which gives J2EE servers the ability to take a great deal of grunt-work off of the shoulders of the application. Describe how containers are able to provide enterprise features to compliant application components, such as remote connectivity, scalability, availability, security, and transaction support. Explain the use of XML for deployment descriptors as a way of reducing programming workload and communicating with the J2EE application server. Understand the deployment process and know the general structure of Web, EJB, and enterprise archive files. Course Duration: 1 day. Prerequisites: some prior experience with business software is assumed, but there are no formal prerequisites for this course.
