Mobile Web Dynpro


What is Mobile Web Dynpro

Ans: SAP Web Application Server allows direct online access to Web Dynpro applications using mobile devices. As part of the SAP Web Application Server, Web Dynpro provides a development and runtime environment with which you can quickly and simply create professional user interfaces for desktop PCs or for mobile devices. An appropriate infrastructure and renderer classes are provided for developing mobile Web Dynpro applications for pocket PCs as well as for BlackBerry Wireless Handhelds.

For the development of mobile Web Dynpro applications, the application development therefore uses:

 i)  The same metadata model

 ii)  The same development environment

 iii)  The same functions provided by Web Dynpro - for example, personalization, connecting a back end, user management, and so on.

 Web Dynpro applications for pocket PCs, BlackBerry Wireless Handhelds, and Nokia Series 80 devices are always online applications that run on the J2EE Engine and are displayed in the Web browser of these mobile devices.


 

Does it requires any special software?

Ans : No any additional software or installations are necessary. You develop using the same development environment - the SAP NetWeaver Developer Studio - that you use to program Web Dynpro applications for a desktop browser. In most cases, you can adapt the user interface to fit the small screen of a mobile device. All other functions that provide support, such as context mapping, connecting a back end using RFC, or data binding,  are used in the same way.

What are the Devices Supported?

 Ans: Following is the list of devices and browser recognition in SAP Web Application Server. It also contains the information regarding conectivity to SAP WAS.

 Pocket PCs: The PIE client (Pocket Internet Explorer client), which is made up of a set of renderer classes and is responsible for data and event handling. Pocket PC users require a suitable network or internet access that enables access to the J2EE Engine. This can be implemented using LAN, WLAN, Bluetooth, GSM, or GPRS, for example. Additional hardware is required as well as a service contract with a telecommunications provider

 BlackBerry Wireless Handhelds: The WML client (Wireless Markup Language client), which is made up of a set of renderer classes and is responsible for data and event handling.Users of BlackBerry Wireless Handhelds will generally already have a service contract that includes internet access via a cellular network. Users of such devices need only ensure that all network and technical prerequisites for accessing the J2EE Engine are met.

* Nokia Series 80 devices (Nokia Communicator 9500 and 9300):*The Nokia S80 Client, which is made up of a set of renderer classes and is responsible for data and event handling.Users of Nokia Series 80 devices require a suitable network or Internet access that enables access to the J2EE Engine. This is done by GPRS.
