Overview:

This course provides the ideal starting point for developers just getting into Java EE programming using Eclipse. This course covers programming topics specific to Java Servlets and JavaServer pages (JSP). In addition to covering the basics, this course will cover more advanced topics including JDBC, JSP Standard Tag Library, Model/View/Controller (MVC), and JavaBeans.

Prerequisites: This course is intended for Java programmers who build server-side web applications in leveraging Eclipse to streamline their development cycle. You should understand essential concepts of object-oriented programming and should be able to write simple Java programs with assistance.
