[Java] Pattern instance using an image within a jar file

Hi,

I'd like to instantiate Pattern, but instead of using the path to a standard image file, my image file is stored in a .jar file (which my project has a dependency on)
Is there a way to do this ?

[Context]
I have created a project (P) containing high-level test "steps" that are driven by selenium and sikuli.
Those steps are then called upon by unit test in our main project (A), and also by system test in a QA regression test project (B)
The sikuli captured images are stored in project P.
And are included in P's compiled jar file.
