problem with "Accelerator Wrapper Classes" about JAIimages

I am displaying a frame which contains canvasJAI.

when it run, the console java prints the message :

could not find mediaLib Accelerator Wrapper Classes. Continuing in pure java mode

has anyone an idea about what in my program could be trying calling this classes ? I can send you my code.

thanks......
