An Intelligent Case Tool for Porting Mobile Java Applications

Today, many mobile device vendors offer their own versions of the Connected (Limited) Device Configuration (CLDC 1) and Mobile Information Device Profile (MIDP 2, 3) of the Java 2 Mobile Edition (J2ME 4). In addition, depending on the device characteristics they offer device-specific or series-specific libraries and APIs extending or complementing those specified in the standard CLDC and MIDP. As a result, porting a Java application written for one device to another is often a very tedious and time-consuming task for the developers. We present SeqFinder, an intelligent CASE tool for assisting the porting of Java mobile applications. SeqFinder eases the porting task by automatically generating all minimal method invocation sequences that lead to an object of a specific type, thus relieving the programmer of the effort to manually search the manufacturer-provided SDK Java archives to find how to accomplish a particular task, for example, how to initiate data transfer through a socket or an HTTP connection.
