Enterprise JavaBeans

Course Length: 4 days, $119 per book

Explores the Enterprise JavaBean (EJB) Component Architecture for building multi-tier client/server applications. Java programmers will be able to write and deploy reusable, distributed components and take advantage of the services offered by the EJB infrastructure.

Audience: Java programmers who wish to use Enterprise JavaBeans to develop distributed intranet and internet applications.

Prerequisites: Java Programming and some Java development experience. Familiarity with JavaBeans, RMI and JDBC is recommended.
