Use Mobile Web Studio to create mobile applications bound for BlackBerry devices. The Offline BlackBerry box in the Properties Editor must be selected to indicate that it is for a BlackBerry device in offline mode.
The mobile applications are deployed from Mobile Web Studio to either M-Business Anywhere (AGDB database), or to Mobile Data Service (Config database) as shown in Figure 5-3. For BlackBerry, the mobile applications are stored in the Config database, and are deployed to mobile devices when the BlackBerry user requests synchronization.
An offline client program, which provides an interface to the mobile applications, must be installed on the user’s BlackBerry device. The UA client enables the user to request synchronization; to use the downloaded mobile applications; to request, sort and manipulate data; and to clean out old data and applications. Mobile applications that cannot be viewed from the UA client are automatically opened in the Web browser.
The JVM on the BlackBerry device has an internal limitation of 128K for the amount of data it can process at a time. When syncing large applications, the application is parsed into smaller chunks, if the BlackBerry device has sufficient memory to handle the parsed chunks.
