Transactions on the MIDP Client

---

Introduction

An application written using the MID Profile can get information from a Servlet via the Transaction Engine. From the point of view of the MIDP client, the Transaction Engine is a big black box which returns information after a request is made. That information might be live or old information from a cache, and the request might be done live or in the background. The Transaction Engine handles all the details of the connection and caching, leaving the client with the simpler question of how to choose the data to send, and how to display the data received.

While Simplicity provides easy pages to do this for you, there is also the ability to write the Java code by hand to access the full functionality of the Transaction Engine.
