ConfigParser not included

The command cv.init(config_path)
returns the following error:
No class ConfigParser can be located on the Java class path

Error in cloudcv/init (line 38)
obj.params = javaObject('ConfigParser',configFile);
I am using Matlab in 64-bit windows, if that makes a difference. Perhaps a jar file is missing, or can't be imported?
I have made sure that all the jar files mentioned in the included javaclasspath.txt are on my static java path in Matlab.
Perhaps there is way to upload an image and get results without using this? Can I see an example of the obj and val that are created by cloudcv.init? Maybe I can create them myself.
