Combined Java Web Example: Servlets, JDBC and Graphics

Combined Java Web Example: Servlets, JDBC and Graphics - module J953

Java supports a very wide range of technologies through class libraries and containers. This module provides you with an example of the combination of some of those technologies - servlets, database access and graphics - in order to provide pictorial, dynamic web content without the need for any browser plugins.

This topic is presented on public courses Deploying Java Applications on Linux / Unix, Extra Day
