Good Morning.

I am trying to get the output of a server process executed by java via Runtime.exec(). Here's the code:

import java.sql.*;
import java.io.*;

public class ip {

  public static void main (String args []) {

    Runtime r = Runtime.getRuntime();

    try {

      String  sid = "emsd";
      String cmd1 = "tnsping " + sid + " | grep 'Host' | cut -d' ' -f18 |
cut -d')' -f1";
      System.out.println(cmd1);
      Process p = Runtime.getRuntime().exec(cmd1); 
      int exitValue = p.waitFor();
      System.out.println(p);
      BufferedReader br = new BufferedReader(new
InputStreamReader(p.getInputStream())); 
      String ip = br.readLine();
      System.out.println(ip);

    } catch (Exception e) {
        System.out.println("Generic Exception catch.");

    }
  } // end of main()
}

When I execute it I get:
tnsping emsd | grep 'Host' | cut -d' ' -f18 | cut -d')' -f1 java.lang.UNIXProcess_at_5988f

The output of the command line is:
128.100.1.140

Anyone see what I'm missing?
Just to make this somewhat oracle related...this is part of a hot backup script.
I am trying to grep the ip (and ultimately port) of the listener so I can dynamically generate the connect to the database. :)

Thanks,
