as the topic says - i cannot access the camera on a 6230 by j2me. my sourcecode works on the 6230 emulator and the wtk-emulator, but the 6230 emulator throws an exception (the wtk-emulator does not.):

But the cameramidlet works on the emulator even if it throws an exception. When i try the application on my real 6230 i get an blank form with the forms name but no form element showing the camera-video. My application works on the siemens s65 but it wont work on the nokia.

Even the Nokia example application refuses to work on the real 6230 - it shows an yellow screen saying "cannot create a datasource".

Can anybody help me please, i have no clue what to do.

thanks a lot in advance.
