Class not found exception

[gurucharan]

Hi,

I am using cmudict.0.6d dictionary to convert english words in wave file to text using WavFile.demo. I have made required changes in the config.xml file, but I am getting following error

Loading Recognizer as defined in 'jar:file:/C:/sphinx4-1.0beta2-src/sphinx4-1.0b
eta2/bin/WavFile.jar!/edu/cmu/sphinx/demo/wavfile/config.xml'...

There is nothing to debug here. You just need to understand what is the "classpath" in Java and where classes are searched.

http://en.wikipedia.org/wiki/Classpath_(Java)

In particular you forgot to change Manifest.in and was lazy enough to neither search the forum no google for the problem.
