Enterprise Computing with Java
605.784
Course Description
The course focuses on the Java 2 Platform, Enterprise Edition (J2EE) for developing multi-tier distributed applications. The course initially explores the Java APIs used by server-side applications. Topics include Java Database Connectivity (JDBC) for portable access to corporate databases, Java Naming and Directory Interface (JNDI) for location of system resources, and Remote Method Invocation (RMI) for distributed invocation of services. CORBA in Java 2 is briefly explored as an alternative to RMI. The course then focuses on the Enterprise Java Beans (EJB) model for transaction-aware business components. Using a commercial application server, students will design and implement a significant programming project using session and entity beans, the Java Transaction API, and the APIs covered in the first half of the semester. Additional topics covered may include the Java Message Service (JMS) for publish-subscribe applications and security issues for distributed Java systems.
