Hi. I've written a simple programm, but it don't work(sorry for my english:)):

          if(msg.message.length()!=0) {
               if(msg.hostname.length()!=0) {
                    try {
                         Process proc = Runtime.getRuntime().exec("echo " + msg.message
                                                                                                                                  + " | smbclient -M " + msg.hostname);
                         } catch (java.io.IOException e) {
     public static void main(String[] args) {
          try
               MsgFormat mess = new MsgFormat();
               System.out.println("Enter hostname: ");
               BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
               mess.hostname = in.readLine();
               System.out.println("Enter your message: ");
               mess.message = in.readLine();
               send(mess);
          catch (java.io.IOException e) {}
}

The exec method isn't a shell. Try with something like this:String[] exec = {"/bin/bash",
                 "-c",
                 "echo "+msg.message+" | smbclient -M "+msg.hostname};
Process proc = Runtime.getRuntime().exec(exec);
