rsync - Mar 2009 - Pipe creation problem: From Java app using rsync + ssh on windows with cygwin

Hello,

I'm having trouble calling rsync from java on windows vista with cygwin
installed.
Its strange as pasting the exact same command into a command shell works
fine.

My test java call looks like this.
*
String[] envVars = {"PATH=c:/cygwin/bin;%PATH%"};
File workingDir = new File("c:/cygwin/bin/");
Process p = Runtime.getRuntime().exec("c:/cygwin/bin/rsync.exe -verbose -r
-t -v --progress -e ssh /cygdrive/c/Users/dokeeffe/workspace/jrsync/
www.servername.net:/home/dokeeffe/rsync/",envVars,workingDir);
*
Then I start 2 stream reader threads to capture and log the inputStream and
errorStream of the Process p.

Here is the output....
*DEBUG: com.mddc.client.rsync.StreamGobbler - opening connection using: ssh
www.derekokeeffe.net rsync --server -vvtre.iLs . /home/dokeeffe/rsync/
DEBUG: com.mddc.client.rsync.StreamGobbler - rsync: pipe: Operation not
permitted (1)
DEBUG: com.mddc.client.rsync.StreamGobbler - rsync error: error in IPC code
(code 14) at /home/lapo/packaging/rsync-3.0.4-1/src/rsync-3.0.4/pipe.c(57)
[sender=3.0.4]
*
The rsync code where the error happens is pipe.c(57) which is this.
    if (fd_pair(to_child_pipe) < 0 || fd_pair(from_child_pipe) < 0) {
        rsyserr(FERROR, errno, "pipe");
        exit_cleanup(RERR_IPC);
    }

So for some reason fd_pair(to_child_pipe) is < 0 or fd_pair(from_child_pipe)
< 0.

If anyone has any suggestions it would be great as I'm stuck now.
Thanks,
Derek

Thanks Michael,
Yes Its outputing to the java Process's input stream. This normally works.
It works fine in linux.
Maybe a problem with cygwin...

I tried removing the -progress to see if it would help but to no avail.

I think its happening when rsync is opening the ssh pipe to the remote host.
