Continuing Studies in Java Development

Course Overview

Move beyond the basics of developing a Java application into the following areas: Java and distributed objects, Java security, integrating Java with databases and messaging systems, performance, and testing.

Note:

• This course does not cover servlets, JavaServer Pages (JSP), or Enterprise JavaBeans (EJB).

Audience

This is an advanced course for experienced Java developers, who want to obtain more advanced server-side developer skills.
