How To Redirect Output From Java Callout Runtime.exec() To A File On Unix Without Using Process.getInputStream() (Doc ID 430403.1)

Goal

Having some Java code to run an external process like

public class OSCommand{
  public static String Run(String Command){
     try{
        Runtime.getRuntime().exec(Command);
        return("0");
     }
     catch (Exception e){
        System.out.println("Error running command: " + Command + 
                                 "\n" + e.getMessage());
        return(e.getMessage());
     }
  }
}

we want to redirect the output of this process to a file. However, we do not want to have to deal with Java's Process.getInputStream() and Process.getErrorStream() because we do not want to do so much Java coding.

And calling that method with Unix-like input redirection like

OSCommand.Run ("ls -alR >/tmp/allFiles.lst")

cannot work because the Run method only calls the ls command and nothing that would take care of the output redirection.
