Please use latest nutch 1.6.
Then, if you still see the same problem, to start debugging the issue,
print the invocation statement in bin/nutch script. ie. add this at the end
in the script:
echo `$EXEC_CALL $CLASS "$@"`

This will show you all the classpath entires. My initial guess is that you
have some directory structure (java home or nutch) with its name having a
space character.

PS: Cygwin is a *horrible* way around for working on shell. In all honesty
there is no substitute for linux rather than running linux :)

Hi Shobha,
The is merely a class loading problem. You need to ensure that the class is
available on your classpath.
Although the problem you are having has nothing to do with this, my advice
is to not use Nutch 1.2.
