Introduction to Java and J2EE Training Course

Introduction to Java and J2EE is a five day class that provides a student with a comprehensive knowledge about Java Programming language. It provides a student with solid knowledge about how to build distributed applications using J2EE platform.

After this class a student will know how different components of J2EE architecture work together.

After this class a student will know how different components of J2EE architecture work together.

There are no prerequisites. However, it is highly recommended for a student to be familiar with at least one programming language.
