I suppose you are trying to follow [the lisp-to-java example here][1] 
for which your error seems to indicate that you haven't included the 
directory of the "Main.class" file.

 From your description here, you seem to have resolved the issue about 
the Main.class not being found but tt isn't clear what you are stuck on 
exactly.  Perhaps you could describe a bit more about what you are 
trying to do, perhaps posting code?

is nothing to compare to it now."
