InetAddress.getLocalHost retrieving 127.0.0.1, not the actual IP Address

Question

I am using the following code :
try{
          InetAddress iaddr = InetAddress.getLocalHost();
          String ipaddr = iaddr.getHostAddress();
          System.out.println("IP= "+ipaddr);
          }catch(UnknownHostException ex){
               ex.getMessage();
to get the IP address of the server on which this code is running.
We are actually trying to set up different machines (other than the Production machine) for Failover of the Application. So, we need to get the IP address of the machine on which the application is running in the code.
For one machine, the above code works perfectly OK.
But, for the three Production machines, the IP address that we are retrieving using the getLocalHost function is fetching the localhost and not the IP address of the machine. That is instead of fetching the IP � a.b.c.d (I am not writing the actual IP in this mail :) ) ... it is fetching the localhost 127.0.0.1 .
So we need to find out a way to fetch the actual IP address so that failover can work.
FYI, all of the machines are Solaris machines.

I am putting up the contents of the /etc/hosts files of the 3 machines I am using.
@@@@ Machine #1 (Code running OK for this, retrieving a.b.c.155 for InetAddress.getLocalhost().getHostAddress()) @@@@
