The COBOL program has to be transormed in a WebService REST stateful. This objective is achieved through a new internal class that allows to communicate with HTML pages through AJAX retrieving data and printing results.

The UI is rendered on mobile devices using the WebView component available on Android ADT while the COBOL logic runs locally on the device thanks to the new Framework library provided along with isCOBOL Mobile. Such library is compatible for Android version 3.0 or greater and also allows to interact with API functions of your mobile devices such as Phone Book, Memo, etc.
