Rsync from Runtime.exec

Question

I'm trying to run following command with Runtime.exec:
rsync -auz sourceHost:'path1 path2' tmpSo I have following code to run this command:
command[0] = "rsync";
command[1] = "-auz";
command[2] = "sourceHost:'path1 path2'";
command[3] = "tmp";
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(command);
InputStream stdin = proc.getErrorStream();
InputStreamReader isr = new InputStreamReader(stdin);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) {
      System.out.println(line);
stdin = proc.getInputStream();
isr = new InputStreamReader(stdin);
br = new BufferedReader(isr);
line = null;
while ( (line = br.readLine()) != null) {
      System.out.println(line);
int exitVal;
try {
      exitVal = proc.waitFor();
} catch (InterruptedException e) {
      throw new IOException(e.getMessage());
if (exitVal != 0) {
      throw new IOException("Exit value was " + exitVal + " that means an error occured" +
          " during rsync call");
}What happens is that when I run the code rsync gives me following error:
rsync: link_stat "path1 path2" failed: No such file or directory (2)
rsync error: some files could not be transferred (code 23) at main.c(812)
client: nothing to do: perhaps you need to specify some filenames or the --recursive option?
java.io.IOException: Exit value was 23 that means an error occured during rsync call
        at RSyncTest.rsyncBinaryData(RSyncTest.java:156)
        at RSyncTest.main(RSyncTest.java:80)Can anyone think of what's wrong here?
Regards and Thanks,

In Java version 1.3 (and later) method exec() of class Runtime returns a Process instance when invoked. The process object returned is what you need to manage.
