Java .dll library path issues

I am trying to use a java archive(.jar) which makes use of a number of external .dlls to control a PCI video framegrabber card. I know the card is installed correctly, because non-matlab software has used the same .jar and .dlls successfully. However, I am trying to integrate the image acqusition with matlab code that analyzes and reports on the data (without great success).
I can confirm that matlab is talking to the .jar, because it successfully generates the top level object used by the interface.
When I try to use the methods to go further, I get an error claiming that the relevant .dll(s) cannot be found. I have tried adding C:/ATP/bin (the path of the appropriate .dlls) to C:\Program Files\MATLAB\R2011b\toolbox\local\librarypath.txt, but the .dll is still not found.
What additional steps may be necessary to ensure that matlab can find my .dlls?
Thanks in advance.

Try adding the path to the DLLs to the system PATH variable and restart MATLAB.
