Abstract: A system and method of porting a reference application to a target mobile device are disclosed. The method includes: a) injecting a first instruction set into the reference application, where the first instruction set instantiates a MIDlet proxy object for a MIDlet object in the reference application; b) injecting a second instruction set into the reference application, where the second instruction set instantiates a Canvas proxy object for a Canvas object in the reference application; b) executing the reference application modified with the first and second instruction sets. The executing step includes: (i) storing a number of events on a data structure, where the events relate to the MIDlet and Canvas objects; (ii) generating an execution thread for sequentially executing the events stored in the data structure; and (iii) executing the execution thread.

Abstract: A method of modifying the graphics output of an application written for a reference mobile device in order to optimize the graphics output for a target mobile device is disclosed. The target mobile device has a display having different characteristics from the reference mobile device. The method includes the following steps: a) loading the application on the target mobile device; b) executing a portion of the application on the target mobile device, such that the graphics output of the application is displayed on the display of the target mobile device; c) storing an instruction from the application which produces the graphics output; and d) changing the instruction by user input from the target mobile device.

Abstract: A method and system of generating target applications from Java reference applications for a particular combination of mobile devices is provided. The method includes the steps of: a) unpacking the reference application into a number of class files; and b) transforming the reference application into the target application by a device plug-in. The device plug-in is capable of transforming different reference applications into corresponding target applications for a particular combination of the reference mobile device and the target mobile device. The system includes a transformation engine and a device plug-in corresponding to the reference/target mobile device combination. The device plug-in includes an XML file and pieces of software code to modify corresponding portions of the reference application not supported by the target mobile device.
