Question: What is the role of wireless Java?
Answer: So how do we deliver these new services? In order to achieve a return on their investment, operators and service developers need to create and deploy services and applications rapidly and reliably, and they must target a wide range of devices. Furthermore users and operators must be confident that services and applications are secure.
Symbian mobile phones are "intelligent clients", so they don't have a thin client's dependency on a network connection. Instead, by making good use of local resources such as databases, messaging, and telephony, together with good processing power, Symbian devices can deliver functionality both off-line and on-line. For instance a route planning application will generally work from locally stored routes and data, and only go on line when it needs to update a route.
Our goal is to provide a Java environment that will enable operators and services provides to create revenue through rich, exciting, value added services. We are achieving this by exposing the advantages and strengths of Symbian OS to Java developers, through APIs, that, by and large, are standard. Many of the newer wireless Java APIs, such as multimedia, messaging, Bluetooth, and PIM, are interfaces onto native functionality, which means that a Java implementation is only as good as the underlying platform.
However Java on Symbian devices is compelling even for operators and application developers writing to the common MIDP APIs. Larger screens, fast performance, and the way Java applications are integrated with native Symbian applications, results in a better user experience.
