Ramneek,

First off, <http://cygwin.com/acronyms/#PCYMTNQREAIYR>.  Thanks.

To answer your questions:

1) I meant the latter if you invoke Java directly.  If you use the wrapper 
scripts, you should use the POSIX paths -- the script will take care of 
the conversion.

2) I was thinking more of setting it from perl via %ENV before the java 
invocation.  And yes, you should either use the forward slashes or escape 
the backslashes in this case.

3) No, Windows API functions understand forward slashes in paths just as 
readily as backslashes.

HTH,
	Igor
