[JAVA3D] Urgent - Please Help!!

[PK]

Hi all,
    I've been trying for ages now to texture a jpeg image onto an object
file (.obj) that I have loaded in to a 3D scene, but I still haven't
managed to do it. At the end of this text is the code I have for loading in
the object file (done using a frame to select the file you want).
I have tried various methods, that seem to make sense, but they didn't work.
Could somebody add in the extra bit needed that will actually texture a
jpeg image onto this object? I only have 1 weeks work left, so I really
need to get this done!

Thanks a million for any help you may give.


Here's the code that loads the object file:
