Igor,
Thanks for your response.
The java command is being executed by backtick operators `.
Questions:
1)Can you please clarify  the use of the forward slash(/) that you
Mentioned in one of your replies to my earlier email ? I am not
Sure if you mean that I convert it totally to a unix style or did
You mean C:/abc/def/myfile.jar ? 
2)I had set the CLASSPATH thru the Advanced Tab from ControlPanel ->
System.
Should the CLASSPATH be reset the same way with forward slash ?

3)Would the java program need to be recompiled using the new style of
Classpath ? 

Thanks!

You didn't say exactly how you're invoking the java process, so
depending 
on what you do, there may be multiple solutions.  If you use system(), 
either quote the '\'s by using more '\'s (see the perl manpage) or set 
CLASSPATH in the environment, or use a suitably modified version of the 
java wrapper script that I posted to this list earlier (see 
<http://cygwin.com/ml/cygwin/2003-01/msg00174.html>).
