What all this IIMA grad learnt after his degree(story about Siddharth and Nidhi)

2010-12-18T18:23:00.000+05:30

The last thing you know Indian Institute of Management, Ahmedabad for, is its love stories. But there was this love story that made news in 2004-2005, about Siddharth Choudhary, from IIMA (then an undergrad) and Nidhi from a college near-by. Then, people said their love story was sweet and that it would weather all storms.

Months later, the couple did weather a huge storm when Nidhi was diagnosed with cancer. The duo came out strong and unscathed from it and this journey is now encompassed in a book titled ‘Eagle Spotted, Message Decoded.’ The book is written by Siddharth and has just about hit the stands.

Siddharth told Pagalguy that much of his learning in life happened after his graduation from IIMA. “There are lots of things you don’t learn at a management school. Life tests you and you have to learn quickly without any prior training. But yes, my MBA degree gave me the confidence to bounce back in life,” he said.

Girl met boy

Siddharth first spotted Nidhi at a small time tea stall just along side the IIM-A campus boundary wall. Ram-bhai’s ketli, (Gujarati name for a tea-stall) has always been life line for students of the institute for sutta and chaiany time of the day or night. Nidhi was visiting the ketli with some of here college friends. There started the little college romance between the two, Nidhi being a localite and studying in a city college.
After graduation in 2005, Siddharth and Nidhi got married and started living in Mumbai. As part of final placements, Siddharth got placed with Monsanto India Limited in Mumbai in a marketing role. Later he moved to Johnson and Johnson, Mumbai, also in the marketing line.

Life took a U-turn

Life seemed perfect.An IIMA degree to boast about, a plush job and home and a loving wife. But about a year or so after marriage, Nidhi was diagnosed with a rare brain tumour called Medulloblastoma. “We were also told it was an aggressive tumour for which there was no cure in allopathy,” said Siddharth.
Nidhi’s case got further complicated because the tumour had spread from origin to spine, making her case even more rare. This was the beginning of a rather tumultuous journey for the couple, where they realised that no degree prepares you for these situations.

Nidhi went through agonising pain and constant black-outs. She was finally operated in Mumbai. Post the operation however, Nidhi was moved to Ahmedabad for chemotherapy and post-operative treatment as her parents were there. “I travelled every weekend to see her and made it for every doctor’s appointment. But I realised, she needed me more than just these visits. The doctors were giving up on her and I decided to take that one big step,” recalls Siddharth.

Good-bye job

The IIMA grad just chucked away his well-paying job and went to Ahmedabad to be with his wife. “Everyone told me I was doing the wrong thing. My parents, colleagues and all our friends. But I was adamant. My wife needed me more. When and if things turn out well, my degree will get me another job, I justified to myself,” Siddharth told Pagalguy.

In Ahmedabad, Siddharth spent many sleepless nights with Nidhi since the chemotherapy sessions were painful. That was when Siddharth told her stories about IIMA days and the days before IIMA when he was a marine engineer. “After a few such sessions Nidhi told me to pen down my little stories in a book. Since I used to wait for Nidhi to sleep first and then sleep myself, I used that time to jot down my stories in my diary. I thought then that my stories were too simple and only meant for Nidhi to cheer-up,” said Siddharth.

The coming days turned out to be worse. “One after another, the doctors began giving up on Nidhi and at that time I wanted to throw the diary out,” recalls Siddharth.

Hope returned

But hope came again. A doctor in Kolkata took up Nidhi’s case and slowly and surely life came back into her body. Regular doctor visits, a strict control on diet and proper medicine intake made Nidhi come back on track. Today after many months, Nidhi is off medicines too. “Somewhere during Nidhi’s recovery, I came back to Mumbai and almost immediately got a job again. I guess I owe that to my management degree. Today Nidhi is also in Mumbai and our life has started again,” said Siddharth.

MBA degree

“There were many lessons from IIM-A that might have helped me during my crisis. It teaches you to deal and live in pressure, race against time and win most times. But one thing that come to my mind when I look back at my years at IIM-A, I feel my course would have been complete if I was also taught life skills. How to deal with people and their inflated egos, how to lead and make people see the bigger picture as you see it. Education needs to go beyond careers, placements and packages”.

(Siddharth’s book, ‘Eagle Spotted, Message Decoded’, is the story of a marine engineer who on his first job on the ship lacks confidence to face life at sea. The book is on how he learns to gather his strengths and overpower his fears – exactly what he did when he learnt of his wife’s cancer. Siddharth himself is a trained marine engineer who sailed for over three years before joining IIM-A. The book is dedicated to his wife.)

GOD - General Operations Director (NS 2 Wireless Networks Simulation)

2010-12-03T00:05:00.004+05:30

GOD is general operations director who is aware of whole network topology.
Here god sets the dist (# hops) between node 0 and node 4 to be 1.
( but why/where is this information used??-answer awaited from CMU. )

The General Operations Director (GOD) object is used to store global

information about the state of the environment, network, or nodes that an
omniscent observer would have, but that should not be made known to any 
participant in the simulation. 

Currently, the god object is used only to store an array of the shortest 
number of hops required to reach from one node to an other. The god object 
does not calculate this on the fly during simulation runs, since it can be 
quite time consuming. The information is loaded into the god object from the 
movement pattern file where lines of the form.

$ns_ at 899.642 "$god_ set-dist 23 46 2 are used to load the god object with the knowledge that the shortest path between node 23 and node 46 changed to 2 hops at time 899.642.

The generator for creating node movement files are to be found under "~ns/indep-utils/cmu-scen-gen/setdest/" directory local ns2 installation. Compile the files under setdest to create an executable. run setdest with arguments in the following way:
./setdest -n num_of_nodes -p pausetime -s maxspeed -t simtime -x maxx -y maxy outdir/scenario-file
Note that the index used for nodes now start from 0 instead of 1 as was in the original CMU version, to match with ns’s tradition of assigning node indices from 0.

Emptiness!!(Lonely) Rohan Rathore IIT Guwahati (Lyrics and Chords)[tune mere jana kabhi nahi jana ishq mera dard mera..]

2010-11-30T18:52:00.017+05:30

A song sung by ROHAN RATHORE from IIT Guwahati and he was suffering from cancer. He sang this song for Supriya a girl he loved more than anything and anyone in the world. Unfortunately she didn't return his love but this song was something he felt he had to do. He died just 15 days after recording this song. ( awesome song!! ♥ ♥ )

Oh love of mine, with a song and a whine,

You're harsh and divine like truths and a lie.

But the tale ends not here

I have nothing to fear

for my love is a yell of forgiving and hold on.

In the bright emptiness, in a room full of it,

is a cruel mistress - my heart!

I feel this unrest, that nests all hollowness,

for I have nowhere to go and I'm cold.

And I feel so lonely yeah...

There's a better place than this: emptiness.

And I'm so lonely yeah...

There's a better place than this: emptiness yeah...

Aa.. aa.. aa...

Tune mere jaana.., kabhi nahin jaana..,

Ishq mera, dard mera.. haaye..

Tune mere jaana, kabhi nahin jaana,

Ishq mera, dard mera

Aashiq tera...

Bheed mein khoya rehta hai...

Jaane jahaan....

Poocho toh itna kehta hai -

That I feel so lonely yeah...

There's a better place than this: emptiness...

And I'm so lonely yeah...

There's a better place than this: emptiness yeah... ya..

Aa.. aa.. aa...

/*English Translation of the Hindi Section of the Song*/

Tune mere jaana, kabhi nahin jaana, (You, my love, have never ever realized)

Ishq mera, dard mera (my love, my pain)

Tune mere jaana, kabhi nahin jaana, (You, my love, have never ever realized)

Ishq mera, dard mera (my love, my pain)

Aashiq tera... (Your lover)

Bheed mein khoya rehta hai... (remains lost in the crowd)

Jaane jahaan.... (My dear love, wherever ...)

Poocho toh itna kehta hai - (... asked, he just says ...)

That I feel so lonely yeah...

There's a better place than this: emptiness.

And I'm so lonely yeah...

There's a better place than this: emptiness yeah...

More about the song and the lyrics:


The track starts with an amazing combination of synthesizer and guitar. The work of the lyricist and singer of this song is simply "awesome". Pain just oozes out through the "alaap" in the reprise.





At last, I would just say that I loved this song, and hope all of you do like this song, I feel sad for the loss of such a promising talent of India, but more than that I feel proud of this guy. Hope the girl realizes the love of Rohan for her, maybe that was what he wished for ........





[NOTE] The authenticity of the story is not confirmed. It is based on what is spread over the internet through various blogs .
Other people who claims this song haven't been able to come up with a proof, until then we have decided to stick to this story. 






As per information on some blogs I got to know that the original composer of this song is Gajender Verma, and due to this very reason he is now claiming legal copyrights to this song. Some of the Emptiness videos on YouTube have been removed due this very reason. Aseem Ahmed Abbasee and Moonami Roy have written this song.  So the whole story about Rohan Rathore has been cooked up for publicity of the track.

[NOTE] Folks I got to know of it from some blogs and social networking sites.







Now here is the true story behind Rohan Rathore





Some of the people( who wanted to earn by charging people for downloading this song) knew the song was good. But an underground track does not reach a wide audience easily.So they needed some means to publicize this song. Then they thought of attaching a story to it. And they munched up a story that had all the elements that typical Bollywood type movie has. It had all the elements COLLEGE, LOVE and then CANCER. It is more or less Karan Johar type masala movie material. Those people very well knew that they should target the younger generation. So they made up a story to target these people. And India these sort of eye-catcher romantic story spreads virally. And finally those morons who wanted to get share out of profits of this cheap and shameful publicity stunt had with them real good marketing strategy. And also the promotion using social networking sites helped them in their viral marketing campaign. So in short the melodrama around so called IIT-G student "Rohan Rathore" is just a cheap marketing strategy.

I can only suggest that youths nowadays should reason the authenticity of such story like "Rohan Rathore" before believing them as most of the times they are the means adopted by some idiots in-order to reap profits.







BUT STILL IN MY HONEST OPINION I WOULD REQUEST EVERYONE TO KEEP ASIDE THE CONTROVERSY BEHIND THIS SONG, AND JUST ENJOY THE TRACK.

Database required by Mapbender needs administrative privileges. There is an install-script that creates the database and creates tables and content

install_2.6.sh.

./mapbender/resources/db/install_2.6.sh

Apache virtual directory

After installation create a virtual directory. Edit /etc/apache2/sites-available/default:

Alias /mapbender /var/www/apache2-default/mapbender_2.4.3/http/

       
          Options MultiViews
          DirectoryIndex index.php
          Order allow,deny
          Allow from all

You must reload (or stop and restart) the Apache program after making changes to the configuration file to make them take effect.

sudo /etc/init.d/apache2 stop
sudo /etc/init.d/apache2 restart

If you want to enable directory browsing, e.g. for debugging purposes add Indexes to the Options line.

Make sure you have loaded the required modules (for example, Ubuntu and Apache2)

a2enmod deflate
a2enmod headers
a2enmod setenvif (for BrowserMatch)

PHP Configuration

You might have to make some adjustments to the file php.ini. Changes in the php.ini also become operative only after restarting the Apache web server !

sudo /etc/init.d/apache2 restart

1. During the test and installation phase of Mapbender it can be helpful log php-errors. Configure the file php.ini as follows:

error_reporting  =  E_ALL & ~E_NOTICE
log_errors = On
error_log = "/var/log/php.log"

2. Check the following details in php.ini allow_url_fopen parameter:

extension_dir = (path to extensions-directory)
allow_url_fopen = On

3. Mapbender manages access authorization in SESSIONS. Check the following details:

session.save_handler = files
session.save_path = (Path to SESSIONS-Directory). (Check authorisation!)

4. Further details of session management should be customized according to server load (see 'garbage collection' in php.ini)

5. With regard to other modules the extension gd2 should be included in the installation and configuration process.

extension=gd.so              (Linux)

# sudo apt-get install lbgd2-dev

6. For some Mapbender modules access to a PostgreSQL database is required. If these modules should be used, you have to check the availability of the required extension in the php.ini file:

extension=pgsql.so           (Linux)

7. short_open_tag

short_open_tag = OFF

8. Mapbender requires simplexml and dom for XML parsing. If not installed, this will lead to some hard-to-find bugs, because PHP fails to throw exceptions! These modules should be already installed if you are using a Linux distribution, but if you compile PHP yourself you need to include these as well

Mapbender Database

Mapbender offers an install-script (install.sh) that sets up the database for you. The following descriptions shows what is happening.
Mapbender offers an update script (update.sh) that keeps your database upoto-date

PostgreSql Database

The user under which you load the database must have Postgres superuser rights during inserting the psql_*.sql files below so it can temporarily disable constraint triggers during insert.

You have to decide to either use UTF-8 or ISO-8859-1 character encoding.

database with UTF-8 encoding

createdb -E UTF8 mapbender

database with ISO-8859-1 encoding

createdb -E Latin1 mapbender

First load the empty Mapbender table definiton (schema)

psql -f pgsql_schema.sql

Then load the data in mapbender/resources/db/postgresql/ - be sure to use the dump with the correct enconding!

UTF-8

psql -f pgsql_data.sql  (in subfolder utf8/)

ISO-8859-1

psql -f pgsql_data.sql  (in subfolder iso/)

At the end set the constraints and sequences. Here you have to check which PostgreSQL version you are using:

pgsql_serial_set_sequences.sql (for 8.x)

psql -f pgsql_serial_set_sequences.sql

You can install PostGIS as follows (as User postgres (su postgres)):

createlang plpgsql (already installed in Mapbender >= 2.5)
psql -f lwpostgis.sql -d (change into the PostGIS directory!)
psql -f spatial_ref_sys.sql -d (change into the PostGIS directory!)

How to load the sqls in PostgreSQL: You find the SQL: /mapbender/resources/db/postgresql/
Notice: There is a difference between the ISO-8859-1 or UTF-8 data-files. Make sure you choose the right folder (iso or utf8)

psql -f pgsql_schema.sql mapbender
psql -f pgsql_data.sql mapbender
psql -f pgsql_serial_set_sequences.sql mapbender

Check the PostgreSQL log file for any errors during insert.
If you want to update from Mapbender Version 2.2.2 to Mapbender Version 2.2.3 load the sqls in the folder update

one column var_name in table gui_element_vars has changed
new table mb_user_wmc
update of the mapbender guis (admin1, admin2_de, admin2_en, gui and gui1. Notice, that gui_de und gui1_de are not longer part of the standard guis. We want to solve the multilanguage problem with element vars in the following versions)

Mapbender Configuration File mapbender.conf

You find the Mapbender Configuration File in the directory "conf". Here you find the file mapbender.conf-dist. Rename the file to mapbender.conf.
Choose the database you want to use (from Mapbender 2.7 on only PostgreSQL is supported):

define("SYS_DBTYPE", "pgsql");

If you use PostgreSQL type your database information here (here is an example):

else {
   define("DBSERVER", "localhost");
   define("PORT", "5432");
   define("DB", "mapbender");
   define("OWNER", "mb");
   define("PW", "mb");
}

perpared statements (PHP > 5.1.x, PostgreSQL > 7.4) define("PREPAREDSTATEMENTS",true);
encoding - default characterset UTF-8 / ISO-8859-1

define("CHARSET","UTF-8");

Define a directory for temporary files, this directory must have write access

define("TMPDIR", "../tmp");

URL for login (test this link to know if your mapbender software is running )

define("LOGIN", "http://localhost/mapbender/frames/login.php");
 define("MAXLOGIN", 3);
 $login = LOGIN;

URL to owsproxy (no terminating slash)

define("OWSPROXY", "http://localhost/owsproxy");

type of server-connection curl, socket, http

#define("CONNECTION", "curl");
 define("CONNECTION", "http");
 #define("CONNECTION", "socket");

define("CONNECTION_PROXY", "");
 define("CONNECTION_PORT", "");
 define("CONNECTION_USER", "");
 define("CONNECTION_PASSWORD", "");

security: path to modules

define("CHECK", false);

mail settings for internal mapbender mails Mapbender can communicate with its users by email. For example, when a user lost his/her password, Mapbender can send an email to this person with a new password.

define("USE_PHP_MAILING", "false");
define("MAILHOST", "");
define("MAILUSERNAME", "");
define("MAILPASSWORD", "");
define("MAILADMIN", "");
define("MAILADMINNAME", "");
$mailHost = MAILHOST;
$mailUsername =  MAILUSERNAME;
$mailPassword =  MAILPASSWORD;

Mapbender error logging

Set Mapbender error logging (see possible options below)

define("LOG_LEVEL", "error"); //"off","error","warning","notice" or "all"
define("LOG_JS", "on"); // "on", "alert", "console" or "off"

Internationalisation

define("USE_I18N", true);

Define default language

define("LANGUAGE", "de");   // "en", "de", "bg", "gr", "nl", "it", es"

you can change the translations in the Mapbender.po (mapbender/resources/locale/de_DE/Mapbender.po files if you prefer a different translation.
- You can edit the Mapbender.po files with an editor
- or with poedit
- after changing Mapbender.po you have to compile the Mapbender.mo files again, see gettext (make sure that gettext is installed).

Example - How to compile the Mapbender.mo files
msgfmt resources/locale/de_DE/LC_MESSAGES/Mapbender.po -o resources/locale/de_DE/LC_MESSAGES/Mapbender.mo

Change the Permission of log Folder

Linux : change the permission of log folder to 777 so that php script can write logs in it.

chmod -R 777 log

Check the Setup

You can check your setup with the script mapbender_setup.php. The script mapbender_setup.php moved to the directory:
/mapbender/tools/mapbender_setup.php
To access the script you have to move it temporary to /mapbender/http/tools/mapbender_setup.php.

Please notice that for security reasons the directory tools should not be available for external users, as e.g. the mapbender_setup.php displays internal information about your system (PHP version, databasename, database user...). You can protect the directory by htaccess or just remove the tools-directory again after testing.
Run the mapbender_setup.php:
http://localhost/mapbender/tools/mapbender_setup.php
The mapbender_setup.php checks wether all configurations of the mapbender.conf are right and checks some system settings.

After the installation - first Login
After the installtion you can login with the user account root and the inital password root. Make sure to change this password asap in order to secure your Mapbender installation. Go to admin2_en Create and edit user to change the password.
You should not delete the user root. To administrate your applications you should create a new user f.e. admin which you use instead if user root.

If you feel any installation instruction that is causing trouble to you, then feel free to comment on this post. I will surely try to answer them when I get some time :)

#create all databases and accounts which will be used by specific PHP applications.
#should be emphasized that these accounts should have access rights only to the databases which are used by the PHP applications
#should not have any access rights to the mysql database administrative privileges (FILE, GRANT, ALTER, SHOW DATABASE, RELOAD, SHUTDOWN, PROCESS, SUPER)

TCP and UDP Client Server Programs In JAVA

2010-02-16T08:14:00.002+05:30

A Simple Server and Client Examples

A simple client and the server programs are explained for all the types of techniques. A code samples for the connection-oriented, next for the connectionless and then for broadcasting are as follows.

Connection-oriented Client and Server : ( TCP )

The client sends the message " Hi from client " and the server response will be " Hello from Server ".

Server Program

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

public class Server{

//port number should be more than 1024

public static final int PORT = 1025;
         
public static void main( String args[])
{

 ServerSocket sersock = null;
 Socket sock = null;
 System.out.println(" Wait !! ");

 try
 {
  //  Initialising the ServerSocket
  sersock =  new ServerSocket(PORT);
                
  // Gives the Server Details Machine name, 
  Port number

  System.out.println("Server Started  :"+sersock);

  try
  {
                        
   // makes a socket connection to particular 
   client after 
   // which two way communication take place

   sock = sersock.accept();

   System.out.println("Client Connected  :"+ sock);

   // Receive message from client i.e Request 
   from client

   DataInputStream ins = new                 
   DataInputStream(sock.getInputStream());
   // Send message to the client i.e Response

   PrintStream ios = new   
   sPrintStream(sock.getOutputStream());
   ios.println("Hello from server");
   ios.close();

   // Close the Socket connection 
        
    sock.close();

    }
 catch(SocketException se)
 {
    System.out.println("Server Socket
  problem  "+se.getMessage());
    }
 catch(Exception e)
 {
    System.out.println("Couldn't start " 
                  + e.getMessage()) ;     
    }               
                        
 // Usage of some methods in Socket class

  System.out.println(" Connection from :  " + 
  sock.getInetAddress());
                
 } // main 
        
}  // Server class

Client Program

import java.lang.*;
import java.io.*;
import java.net.*;
import java.net.InetAddress;


class client
{
 Public static void main(String args[])
 {
 Socket sock=null;
 DataInputStream dis=null;
 PrintStream ps=null;
 System.out.println(" Trying to connect");
                                   
 try 
 {
 // to get the ip address of the 
 server by the name
              
 InetAddress ip =InetAddress.getByName
 ("Hari.calsoftlabs.com");

 // Connecting to the port 1025 declared 
 in the Serverclass
 // Creates a socket with the server
  bind to it.

  sock= new Socket(ip,Server.PORT);
  ps= new PrintStream(sock.getOutputStream());
  ps.println(" Hi from client");
  DataInputStream is = new 
  DataInputStream(sock.getInputStream());
  System.out.println(is.readLine());

 }
 0catch(SocketException e)
 {
  System.out.println("SocketException " + e);
 }
 catch(IOException e)
 {
  System.out.println("IOException " + e);
 }

  // Finally closing the socket from 
  the client side

 finally
 {
 try
  {
   sock.close();
  }
  catch(IOException ie)
  {
   System.out.println(" Close Error   :" + 
   ie.getMessage());
  }               
 }  // finally 
                        
} // main 
}   // Class Client

Running the Server and Client

After you've successfully compiled the server and the client programs, you run them. You have to run the server program first. Just use the Java interpreter and specify the Server class name. Once the server has started, you can run the client program. After the client sends a request and receives a response from the server, you should see output similar to this :

On client side:
   Hello from Server
On Server side:
   Hi from client

Connectionless Client and Server : (UDP)

A datagram is an independent, self-contained message sent over the network whose arrival, arrival time, and content are not guaranteed.

The java.net package contains two classes to help you write Java programs that use datagrams to send and receive packets over the network: DatagramSocket, DatagramPacket, and MulticastSocket An application can send and receive DatagramPackets through a DatagramSocket. In addition, DatagramPackets can be broadcast to multiple recipients all listening to a MulticastSocket.

The following source code demonstrates a slightly more complex server that uses datagrams instead of sockets. After a connection is made, It echoes back whatever is sent by the client instead of simply hanging up the connection. It is Called as echo Server.

Server Program

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


public class EchoServer
{

//Initialize Port number and Packet Size
  
 static final int serverPort = 1026;
 static final int packetSize = 1024;

 public static void main(String args[]) 
 throws SocketException{

 DatagramPacket packet;
 DatagramSocket socket;
 byte[] data;    // For data to be 
 Sent in packets
 int clientPort;
 InetAddress address;
 String str;

 socket = new DatagramSocket(serverPort);

 for(;;){
 data = new byte[packetSize];

 // Create packets to receive the message

 packet = new DatagramPacket(data,packetSize); 
 System.out.println("Waiting to receive 
 the packets");

 try{

 // wait infinetely for arrive of the packet

 socket.receive(packet);

 }catch(IOException ie)
 {
 System.out.println(" Could not Receive
 :"+ie.getMessage());
 System.exit(0);
 }
  
 // get data about client in order to 
 echo data back
  
 address = packet.getAddress();
 clientPort = packet.getPort();
  
 // print string that was received 
 on server's console
 str = new String(data,0,0,packet.getLength());
 System.out.println("Message  :"+ str.trim());
 System.out.println("From   :"+address);
  
 // echo data back to the client 
 // Create packets to send to the client
  
 packet = new DatagramPacket(data,packetSize,
 address,clientPort);
  
 try
 {
 // sends packet   

 socket.send(packet);

 }
 catch(IOException ex)
 {
  System.out.println("Could not Send 
  "+ex.getMessage());
  System.exit(0);
  }
  
 } // for loop

 } // main


} // class EchoServer

Client Program

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


public class EchoClient{
   
 static final int serverPort = 1026;
 static final int packetSize = 1024;
   
 public static void main(String args[]) throws
 UnknownHostException, SocketException{
 DatagramSocket socket; //How we send packets
 DatagramPacket packet; //what we send it in
 InetAddress address; //Where to send
 String messageSend; //Message to be send
 String messageReturn; //What we get back 
 from the Server
 byte[] data;
       
 //Checks for the arguments that sent to 
 the java interpreter
 // Make sure command line parameters correctr
       
 if(args.length != 2)
 {
 System.out.println("Usage Error :
 Java EchoClient < Server name> < Message>");
 System.exit(0);
 }   
       
 // Gets the IP address of the Server
 address = InetAddress.getByName(args[0]);
 socket = new DatagramSocket();
               
 data = new byte[packetSize];
 messageSend = new String(args[1]);
 messageSend.getBytes
 (0,messageSend.length(),data,0);
               
 // remember datagrams hold bytes
 packet = new
 DatagramPacket(data,data.length,address,serverPort);
 System.out.println(" Trying to Send the packet ");
               
 try
 {
  // sends the packet
               
  socket.send(packet);
           
  }
  catch(IOException ie)
  {
  System.out.println("Could not Send :"+ie.getMessage());
  System.exit(0);
  }            
       
  packet is reinitialized to use it for recieving
       
  packet = new DatagramPacket(data,data.length);
               
  try
  {
  // Receives the packet from the server
                   
  socket.receive(packet);   
               
  }
  catch(IOException iee)
  {
  System.out.println("Could not receive :
  "+iee.getMessage() );
  System.exit(0);
  }       
       
  // display message received
       
  messageReturn = new String (packet.getData(),0);
  System.out.println("Message Returned : "+
  messageReturn.trim());
  }    // main
   
   
 } // Class EchoClient

Running the Server and Client

The client side and the server side networking code looks actually very similar.This is true with many applications that use datagrams because the java.net.DatagramSocket class is used to both send and receive DatagramPackets.

Suppose server running on the machine named Hari.calsoftlabs.com, whereas the client running on the xxxx.info.com. As you can see at the end of the example the server is running waiting for the another connection, while the execution of the client has halted.

Server Side :

To start the server :

Java EchoServer

Output:

Message:Hello
From   :xxxx.info.com

Client Side :

Java EchoClient abhishek-bit.blogspot.com Hello

Output:

Message Returned : Hello
