Executing system commands on Linux

Question

Hi,
I am trying to copy a file from Java code on Linux platform using the cp command.
Process p = Runtime.getRuntime.exec("bash -c \"cp file1 file2\"");
The process is exiting with exit code 2 and the file is not getting copied.
The same command when executed directly from the terminal window (command console of Linux) is working fine and the file is getting copied.
I am using RedHat Linux 7.1. Any ideas plz...
best wishes
Issac

try splitting up the args into an arary
import java.io.*;
public class CP {
  public static void main (String [] args) {
    try {
      String [] cmd = {"/bin/sh","-c","cp file1 file2"};
      Process p = Runtime.getRuntime().exec(cmd);
      p.waitFor();
      System.out.println("exit value " + p.exitValue());
    } catch (Exception e) {
      System.out.println("err : " + e);
}
