Enterprise JavaBeans Using BEA Weblogic Course

- this course is no longer scheduled to run. Please refer to schedule for current course titles.

This intensive hands-on course explores the Enterprise Java Bean (EJB) Component Architecture for building multi-tier internet applications. Java programmers will be able to write and deploy reusable, distributed components and 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. Delegates should have experience of Java Programming and some Java development experience. Familiarity with JavaBeans, RMI, JDBC, Servlets and XML is recommended.
