Disable Java Update Notification





Fed up with getting prompted to update Java, or if you have some web application like Banner that requires a particular version??? You can use a simple registry hack to disable notification of available updates...!!!


(1). Open the Registry Editor by going to the Start button and typing in regedt32.

(2).Navigate through to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Update\Policy

(3).Change the value of EnableAutoUpdateCheck to 0 and the value of EnableJavaUpdate to 0.
Java should no longer prompt you for the annoying updates.



Enjoy..!!!

Is this trick useful??  Comment here..
Thank you.!!  :)

udp communication

Hi Viewer,

Here is a simple java program showing client-server interacion using UDP.
In tgis example, client will send a message and the sever will reply back with same message after converting it to Uppercase..!!



server.java


import java.io.*;
import java.net.*;
class UDPServer
{
public static void main(String args[])throws Exception
{
DatagramSocket serverSocket=new DatagramSocket(1249);
byte[] receiveData=new byte[1024];
byte[] sendData=new byte[1024];
while(true)
{
DatagramPacket receivePacket=new DatagramPacket(receiveData,receiveData.length);
serverSocket.receive(receivePacket);
String sentence=new String(receivePacket.getData());
InetAddress IPAddress=receivePacket.getAddress();
int port=receivePacket.getPort();
String capitalizedSentence=sentence.toUpperCase();
sendData=capitalizedSentence.getBytes();
DatagramPacket sendPacket=new DatagramPacket(sendData,sendData.length,IPAddress,port);
serverSocket.send(sendPacket);
}
}
}










client.java


import java.io.*;
import java.net.*;
class UDPClient
{
public static void main(String args[])throws Exception
{
BufferedReader inFromUser=new BufferedReader(new InputStreamReader(System.in));
DatagramSocket clientSocket=new DatagramSocket();
InetAddress IPAddress=InetAddress.getByName("localhost");
byte[] sendData=new byte[1024];
byte[] receiveData=new byte[1024];
System.out.println("Enter msg:");
String sentence=inFromUser.readLine();
sendData=sentence.getBytes();
DatagramPacket sendPacket=new DatagramPacket(sendData,sendData.length,IPAddress,1249);
clientSocket.send(sendPacket);
DatagramPacket receivePacket=new DatagramPacket(receiveData,receiveData.length);
clientSocket.receive(receivePacket);
String modifiedSentence=new String(receivePacket.getData());
System.out.println("FROM SERVER:"+modifiedSentence);
clientSocket.close();
}
}
