Build a smart J2ME mobile application, Part 1

Naveen Balani spends most of his time designing and developing Java 2 Platform, Enterprise Edition (J2EE)-based frameworks and products. He has written various articles for IBM® developerWorks in the past, covering topics like ESB, SOA, JMS, web services Architectures, CICS, AXIS, J2ME, DB2® XML Extender, WebSphere® Studio, MQSeries, Java™ Wireless Devices, and DB2 Everyplace for Palm, Java-Nokia, Visual Studio, .Net, and wireless data synchronization.

Summary:  This two-part tutorial shows you how to build a mobile database application using the J2ME Record Management System and how to synchronize it with a remote Cloudscape database. You also learn how to craft a MIDlet that performs the necessary logic to create and access the database application and deploy it to a J2ME environment.

About this tutorial

This tutorial is the first in a two-part series designed as a step-by-step guide to building a smart J2ME mobile application. In this tutorial you learn how to build a simple mobile application for order placement. The example application uses the Java 2 Platform, Micro Edition (J2ME) record management system (J2ME RMS) to store order information and a MIDlet to perform the necessary logic of creating and accessing the database application. You learn how to work with the J2ME RMS, craft a MIDlet, and deploy the resulting application to a J2ME environment.

In the next tutorial in this series, you will write your own two-way synchronization logic to synchronize the order information stored in the J2ME RMS with a remote Cloudscape database. The mobile user will then be able to track the status of his or her order by accessing the remote Cloudscape database.


Prerequisites

To gain the most from the information in this tutorial, you should have a good working knowledge of J2ME. Before you start the tutorial, make sure you have the following downloads:

I'll walk you through the installation of the latter two components in the section on Installing the software .
