This course teaches developers how to create J2EE applications using Servlets, JavaServer Pages (JSP), Enterprise JavaBeans (EJB), and Web services. Students will learn how to design and develop J2EE applications, as well as make decisions about when to use the various J2EE components. Students will deploy the applications to Oracle Application Server 10g (OracleAS 10g) using Oracle JDeveloper 10g.
