Austin Stanhope - 2008-11-11

I am running into the following problem when running the sample programs for sphinx 4. Any ideas?

  Thanks but I still get the same errors. It's having issues finding some classes. I followed the instructions to install.

    Hm, are you sure that sphinx4.jar was properly built? Did you unpack jsapi.jar?
