Course Description
Overview
This course is designed to provide students with the knowledge and skills to become productive using Servlets and JavaServer Pages (JSPs), the foundation of Web application development in J2EE. Students will be taught using Live Web-based training and comprehensive practical exercises designed to explain the fundamentals of J2EE Web application development. Completely tool-agnostic, students will rapidly negotiate the learning curve and be ready to write, package and deploy Web applications to a production WebSphere environment.This course can be hosted on a variety of IDEs such as RAD/RSA, Eclipse, MyEclipse Blue, and SpringSource Tool Suite (STS). Please let your sales representative know the IDE you are currently using.
