Need platform independent java code for TNS PING

Question

Hi, I am able to ping server /ip address. but unable to ping some TNS entry.
There is one way to ping TNS entry using System command, but that will make my code platform dependent. i want platform independent code.. need code help for TNS Ping to database server.. here are my code:
---Code for server / Ip address ping:---------
package DBM;
import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.ArrayList;
import oracle.net.TNSAddress.*;
public class PingServer
public static void main(String[] args)
System.out.println(" Server Pinging Starts...");
ArrayList<String> list=new ArrayList<String>();
list.add("g5u0660c.atlanta.hp.com");
list.add("g1u1675c.austin.hp.com");
list.add("gvu1785.atlanta.hp.com");
list.add("10.130.14.109");
list.add("10.130.0.173");
list.add("DESCRIPTION = (SDU = 32768) (enable = broken) (LOAD_BALANCE = yes) (ADDRESS = (PROTOCOL = TCP)(HOST = gvu1515.atlanta.hp.com)(PORT = 1525))(ADDRESS = (PROTOCOL = TCP)(HOST = gvu1785.atlanta.hp.com)(PORT = 1525)");
list.add("IDSENGI");
//This Ipadd variable is used to convert the arraylist into String
String ipadd="";
try
     for(String s: list)
          ipadd=s;
          // InetAddress is class.in this class getByName()is used to take only string parameter.
          InetAddress inet = InetAddress.getByName(ipadd);
          //InetAddress inet1 =InetAddress.getAllByName("IDESENGP");
          System.out.println("Sending Ping Request to " + ipadd);
          //in InetAddress call IsReachabe(3000)method is used to ping the server IP and if ping is successfully then return true otherwise false.
          //IsReachable()take time in millisecond and return type is boolean.
          System.out.println("Host is reachable: "+inet.isReachable(3000));
     System.out.println("Server Pinging program is working fine........");
catch (UnknownHostException e)
     System.err.println("Host does not exists");
catch (IOException e)
     System.err.println("Error in reaching the Host");
----Code for TNS ping using system host----
package DBM;
import java.io.*;
public class doscmd
public static void main(String args[])
try
Process p=Runtime.getRuntime().exec("cmd /c tnsping IDSENGP");
p.waitFor();
BufferedReader reader=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line=reader.readLine();
while(line!=null)
System.out.println(line);
line=reader.readLine();
catch(IOException e1) {}
catch(InterruptedException e2) {}
System.out.println("Done");
The above two codes are working absolutely fine... but need TNS ping program is platform dependent..we need to deploy it in both windows, unix...
Please help.

You don't need to install another JDK, just use the api from 1.2 and you should be fine. You can even use the 1.4 jdk to compile as if it were 1.2 by using the -target option in javac.
