The new command caching feature in WebSphere® Application Server V5 provides the ability to actively cache the results of EJB methods. Storing commands in a cache for reuse by subsequent callers allows requests to be handled in the business logic tier rather than in the data tier, where processing is more expensive. A typical example of a cacheable command is a stock quote that accepts a ticker symbol as an input parameter and produces the stock share price as its output parameter.
This tutorial demonstrates how to use IBM WebSphere Studio Application Developer Version 5.0 to build, deploy, and run an enterprise application using the new command caching functionality in WebSphere Application Server V5.
This tutorial is intended for J2EE developers.
Objectives - Develop a command caching-based application.
- Deploy a command caching application using WebSphere Studio.
- Monitor the performance gains of command caching.
Prerequisites
To get the most out of this tutorial, you should have a basic working knowledge of J2EE programming and WebSphere Studio Application Developer.
System requirements
To perform the tasks described in this tutorial, you will need WebSphere Studio Application Developer Version 5 installed and operational.
