J2EE Programming with WebLogic

Prerequisites:

Delegates should have Java programming and some Java development experience. Familiarity with JavaBeans, RMI, JDBC, Servlets and XML is useful.

Course Description:

This intensive course explores the Enterprise Java Bean (EJB) Component Architecture for building multi-tier internet applications. On completion of the course delegates will be able to:
- Write and deploy reusable, distributed components.
- Take advantage of the services provided by the BEA WebLogic AppServer.

This course is for Java programmers who wish to use Enterprise Java Beans to develop distributed intranet and internet applications in the BEA WebLogic AppServer.

This course includes the following modules:
