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.

Claims

1. A method of porting a reference application to a target mobile device, the method comprising:

a) injecting a first instruction set into the reference application, wherein the first instruction set instantiates a proxy for a first object in the reference application;

b) executing the reference application modified with the first instruction set, wherein the executing step comprises;

i) storing a plurality of events in a data structure, wherein at least one of the plurality of events relate to the first object;

ii) generating an execution thread for sequentially executing the plurality of events stored on the data structure; and

iii) executing the execution thread.

2. The method of claim 1, wherein the storing step comprises serially storing the plurality of events in the data structure.

3. The method of claim 2, further comprising injecting a second instruction set into the reference application, wherein the second instruction set instantiates a proxy for a second object in the reference application.

4. The method of claim 3, wherein the first object is a MIDlet object and the proxy for the first object is a MIDlet Proxy object, wherein the second object is a Canvas object and the proxy for the second object is a Canvas Proxy object.

5. The method of claim 2, wherein the plurality of events comprises a system event and an application event, wherein the system event is configured to execute on a system event thread of the reference application, and the application event is configured to execute on an application event thread.

6. The method claim 5, wherein a JVM forwards the plurality of events to the Canvas Proxy or the MiDlet proxy.

7. The method of claim 6, wherein at least one of the Canvas Proxy object and the MIDlet Proxy object stores the plurality of events on the data structure.

8. The method of claim 1, wherein the data structure comprises an array of event descriptors.

9. A system for porting a reference application to a target mobile device, the system comprising:

a) a first instruction set adapted to instantiate a proxy for a first object in the reference application;

b) an executable software module adapted to inject the first instruction set into the reference application; and

c) a data structure;

wherein the proxy for the first object is adapted to store a plurality of events in the data structure.

10. The system of claim 9, further comprising a second instruction set adapted to instantiate a proxy for a second object in the reference application.

11. The system of claim 10, wherein the executable module is adapted to inject the second instruction set into the reference application.

12. The system of claim 11, wherein the first object is a MIDlet object and the proxy for the first object is a MIDlet Proxy object, wherein the second object is a Canvas object and the proxy for the second object is a Canvas Proxy object.

13. The system of claim 12, wherein the plurality of events comprises a system event and an application event, wherein the system event is configured to execute on a system event thread of the reference application, and the application event is configured to execute on an application event thread.

14. The system of claim 13, wherein at least one of the Canvas Proxy object and the MIDlet Proxy object stores the plurality of events on the data structure.
