Not able to execute external file with parameter using RuntIme

Question

When I try tio execute the following command :
          String command="C:\\Program Files\\BMC Software\\CONTROL-M EM 6.2.01\\bin\\deftable.exe -u abc -p abc567 -s q23.nz.dq.com -src DBIQ-EURILIBORROB.exp";
Process p = Runtime.getRuntime().exec(command);
It gives "File 'DBIQ-EURILIBORROB.exp' is Missing." even though the file is available in the given location. Please help
Regards

Answer 1

Thanks a lot mate.. It works now.. But i had to do a little more changes.
I was getting an exception
java.lang.IllegalThreadStateException: process has not exited
     at java.lang.ProcessImpl.exitValue(Native Method)
     at com.Test.test1(Test.java:94)
     at com.Test.main(Test.java:23)
when my code was like this:
File f = new File ("C:\\Program Files\\BMC Software\\CONTROL-M EM 6.2.01\\bin"); // The working directory - not the file to be processed
String[] command = {f.getAbsolutePath() + "\\deftable.exe", "-u", "abc", "-p", "abc567", "-s", "q23.nz.dq.com", "-src","DBIQ-EURILIBORROB.exp"};
Process proc = Runtime.getRuntime().exec(command,null,f);
int exitVal = proc.exitValue();
} catch (Throwable t){
t.printStackTrace();
But it worked when i changed the code as shown below it worked fine
public static void test1() throws IOException
File f = new File ("C:\\Program Files\\BMC Software\\CONTROL-M EM 6.2.01\\bin"); // The working directory - not the file to be processed
String[] command = {f.getAbsolutePath() + "\\deftable.exe", "-u", "abc", "-p", "abc567", "-s", "q23.nz.dq.com", "-src","DBIQ-EURILIBORROB.exp"};
     Process proc = Runtime.getRuntime().exec(command,null,f);
     InputStream in = proc.getInputStream();
          InputStream err = proc.getErrorStream();
          BufferedReader readIn = new BufferedReader(new InputStreamReader(in));
          BufferedReader readErr = new BufferedReader(new InputStreamReader(err));
          int b;
          int exit = -1;
          boolean bReady = false;
          while (!bReady) {
               try {
                    exit = proc.exitValue();
                    bReady = true;
               } catch (IllegalThreadStateException isex) {
               suckStreams(readIn, readErr);
          readIn.close();
          readErr.close();
          System.out.println("Exit Status :" + exit);
public static void suckStreams(BufferedReader readIn, BufferedReader readErr) {
          try {
               while (readIn.ready() || readErr.ready()) {
                    if (readIn.ready())
                         System.out.println(readIn.readLine());
                    if (readErr.ready())
                         System.err.println(readErr.readLine());
          } catch (IOException ex) {
               System.err.println("suckStreams: " + ex);
     }
