Justin,

Sorry, that was not a correct answer, since you're invoking grep on the 
standard input.


Create a shell script that searches one file at a time and include the -H / 
--with-filename option to grep. It'll be somewhat slower, but presumably 
this isn't something you'll do frequently.


     find /c -iname '*.jar' -exec checkPresence SAXParser.class '{}' \;


Where "checkPresence" is this file:

-==-
#!/bin/sh

unzip -l "$2" |grep -H "$1" >/dev/null && echo "$2"
-==-

You can make checkPresence accept multiple file names, which will speed 
things considerably:

-==-
#!/bin/sh

pattern="$1"
shift

for arg; do
         unzip -l "$arg" |grep -H "$1" >/dev/null && echo "$2"
done
-==-

now you can do this:

     checkPresense SAXParser.class $( find ... )

The only possible problem here is if there are too many files output by 
find. In that case, use xargs.

Justin,

[ This isn't Cygwin-specific. It's just a GNU grep question. ]


% grep --help
...
   -H, --with-filename       print the filename for each match
...
