IBM Workplace Client Technology Micro Edition Version 5.7.1: Application Development and Case Study

Chapter 2. The Case Study: ITSO Car Rentals 25

You will see in this case study, the device is logically some type of mobile

handheld device. In other scenarios, for say an insurance adjuster, this could be

a desktop, mobile computer, or even a handheld device.

2.2 Running the sample application

The sample application is created step by step in the following chapters. Here is

an overview of the completed sample application.

2.2.1 The sample application panels

The sample application has three panels:

򐂰 Login

򐂰 Main

򐂰 Config

Use the Login button to proceed to the main panel. A user ID and password must

be entered. These are not verified locally or remotely in the sample application,

but the same user ID and password are used during DB2 sync. See Figure 2-2.

Figure 2-2 The login panel

The main panel displays the pending and arrived rental customers. Check boxes

display next to each customer so that they can be marked to be moved to the

next state: Pending →Arrived. Arrived →Exited. See Figure 2-3 on page 26.

To record a status change, or just refresh the main panel, along with any

messages that might have arrived, use the Refresh/Submit button.

A Sync button is available to perform a database sync with the server. Although

the sync can complete quickly, there is a delay before the mirror database and

the host database are replicated. After that, the change is displayed on the

server.

A Device Update button is available to call a local agent to update the client

device based on jobs defined on the device management server.

The Logout button returns the user to the login panel.

To configure the demo, use the Config button to navigate to the configuration

panel.

For demonstration purposes, there is a Reset Demo button. This updates the

local database to show that no users have arrived and clears the vehicle location

information.

The config panel (Figure 2-4 on page 27) allows the user to set whether the

demo should be run in stand-alone mode or to use real servers for DB2 sync,

MQe messaging and Web services. The hosts and ports to be used can be

configured on this panel.
