Actually my first question is basically part of my 2nd question. And I was wrong about the input. means, in my network elements(switches, routers) ping/echo services are not enabled.
So the part, I need to know is, how to find out the device
type from the snmp query ? Like, is it a router or ATM switch or firewall or SUN Solaris m/c etc.. ???
Is there any common mib ( mib II ??) or mibattribute
do I need to look ?
Is mib-II should be implemented if it is snmp enabled ?

anything will be appreciated.

Step 1 would require pinging those hosts. If you have access to the services running on all those hosts, you could run the Echo service on port 7, in which case you could use pure Java. Otherwise, you'd have to do a proper ping using ICMP, which would require you to use JNI.

Come back later about step 2!

You could try this sort of thing:

mport java.io.*;
import java.net.*;
class Ping {
public static void main(String[] args) {
BufferedReader in = null;
try {
Runtime r = Runtime.getRuntime();
Process p = r.exec("ping 62.2.78.245");
if (p == null) {
System.out.println("Could not connect");
}
in = new BufferedReader(new InputStreamReader(p
.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
} catch (IOException io) {
System.err.println(io.toString());
}
}
}

Better indentation:

import java.io.*;
import java.net.*;

class Ping {

  public static void main(String[] args) {
    BufferedReader in = null;
    try {
      Runtime r = Runtime.getRuntime();
      Process p = r.exec("ping 62.2.78.245");
      if (p == null) {
        System.out.println("Could not connect");
      }
      in = new BufferedReader(new InputStreamReader(p.getInputStream()));
      String line;
      while ((line = in.readLine()) != null) {
        System.out.println(line);
      }
      in.close();
    }
    catch (IOException io) {
      System.err.println(io.toString());
    }
  }
}
