Summary:  This tutorial series shows how to build a mobile database application using the J2ME Record Management System and later synchronize it with a remote Cloudscape database. This is where you will also learn how to craft a MIDlet that performs the necessary logic for creating and accessing the database application and deploying it to a J2ME environment.

Before you start

About this tutorial

In Part 1 of this tutorial series (see Resources for a link), you built a sample mobile application for taking orders. This application used the JavaTM 2 Platform, Micro Edition (J2ME) Record Management System for storing order information. You also learned how to craft a MIDlet that performs the logic necessary for creating and accessing the database application and saw how to deploy it to a J2ME environment.

In this second tutorial, you'll synchronize the order information stored in the J2ME Record Management System with a remote, open source CloudscapeTM database. You'll build your own two-way synchronization logic. The mobile application will supply all the information necessary for a remote sever-based application to act upon, ship the ordered product, and update the product information in a remote Cloudscape database. The mobile user can track the status of the order by synchronizing with this database.
