Unhappy Problem executing this piped command: JAVA

I want to execute the following command from a java application. As you can see, I want to back up the BACKUP directory (which is located on the user home directory) to a CD without creating an ISO image.

From the shell it works like a charm.

mkisofs  -R  /home/jennifer/BACKUP  | cdrecord -v fs=6m speed=2 dev=0,0,0 -

But obviously my java implementation of that command doesn't work...any inputs are welcome. If you can tweak around my code to see your idea that would be wonderful. Thanks.

try {

 String cmdBurn = "mkisofs -R " + System.getProperty ( "user.home" ) +
                           "/" + "BACKUP " + "| " +
                                   "cdrecord -v fs=6m speed=4 dev=0,0,0 -" ;

  Process listBurn = Runtime.getRuntime ().exec ( cmdBurn ) ;
   catch ( IOException ex ) {

I don't know for sure, but at a guess I think you need to invoke a shell to get the pipeline functionality. Try making your command:

sh -c "mkisofs -R /home/jennifer/BACKUP | cdrecord -v fs=6m speed=2 dev=0,0,0 -"
