Chapter 5: Integrated Products

BlackBerry

You can deploy mobile applications to BlackBerry devices using any of these methods:

BlackBerry Enterprise Server (BES) – use BES documentation from Research in Motion to install BES and integrate with Unwired Accelerator. BES provides Internet and e-mail service.
Mobile Data Service (MDS) – use the MDS component from Research in Motion to deploy mobile applications to BlackBerry devices. MDS provides Internet service, but no e-mail service.

The method are available for deploying mobile applications from Mobile Web Studio to BlackBerry devices:

Offline mode – make sure the Offline BlackBerry box is selected in the Properties Editor in Application Builder. Requires the UA Offline client on the BlackBerry device.
Online mode – use pages and page groups to create a container for the mobile application. See the Unwired Accelerator Developer’s Guide for more information.

Two BlackBerry clients are available for running mobile applications on the mobile device:

UA Offline client – provides access to mobile applications developed in UA and deployed to the mobile device. UA Server stores the list of applications marked Offline BlackBerry. The BlackBerry Offline client sends a Sync All request to the UA Server for the list of applications that has the Offline BlackBerry attribute turned on. You select an application from the list, and Sync the application. The mobile application is cached in memory on the mobile device.
BlackBerry browser – provides real-time access to mobile applications and data. If an application cannot be opened in UA Offline client, the BlackBerry browser is used.

Table 5-1 describes the advantages and disadvantages for using UA Offline client and BlackBerry browsers. Use the information to troubleshoot mobile application problems.

**Table 5-1: UA client versus BlackBerry browser**
Option	Advantages	Disadvantages
UA Offline client	Has better table UI support. BlackBerry browser does not support tables. Has list/detailed view of records. We can control the columns in the list/detail view. Provides offline access to data. The application data is stored in device memory. Access content quicker since data is stored in memory.	Battery dies, you will lose your data. Not live application content. Requires network connection to sync. Has transfer size limits from MDS/BES.
BlackBerry browser	Real time access to data. Application data is always up-to-date because it is always online. No need to sync.	Cannot access application content if you are out of range (no network connection). Need to be always connected. Lack of table UI support. Columns are wrapped to the next line.
