Intermediate Java 2 Programming (3 days)
Description
This courseware training guide book will cover server-side development of Web applications using both servlets and JavaServer Pages (JSP). Due to the ubiquity of databases in such applications, the Java Database Connectivity (JDBC) API is covered in detail as well. Multiple examples and exercises build on student knowledge throughout the course, culminating in complex Web applications utilizing a database.
