I am using BufferedReader for reading a response from the server.

while((String line = br.readLine()) != null)
System.out.println(line);

Above is my code. When I run I am getting only few lines but not all the lines.

If br completes reading a line then it should return null and come out of the loop. That is also not happening. It is just waiting for the line to read.

Any idea why this is happening ?

package testPackage;

import java.sql.Connection;
import java.sql.DriverManager;
import java.util.Properties;

public class Main {

	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
				  
		    try {
		      Class.forName("com.mysql.jdbc.Driver");
		      Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/student?useSSL=true","root","success");  
		      System.out.print("Database is connected !");
			  con.close();				
	}
		    catch(Exception e)
		    {
		    	System.out.println(e.getMessage());
		    	throw e;
		    }
		    	
		    }

}

serverSocket = new ServerSocket(4554);
serverRunning = true;
while (serverRunning) {
    socket = serverSocket.accept();
    ObjectOutputStream dataOut = new ObjectOutputStream(socket.getOutputStream());
    ObjectInputStream dataIn = new ObjectInputStream(socket.getInputStream());
    System.out.println("Done 1");

    String string = dataIn.readUTF();
    System.out.println("Done 2");

    int number = dataIn.readInt();
    System.out.println("Done 3");

    dataOut.writeUTF("String from server");
    System.out.println("Done 4");

    dataOut.writeInt(1);
    System.out.println("Done 5");

    System.out.println(string + " | " + number);
}

Socket socket = new Socket("localhost", 4554);
ObjectOutputStream dataOut = new ObjectOutputStream(socket.getOutputStream());
ObjectInputStream dataIn = new ObjectInputStream(socket.getInputStream());
System.out.println("Done 1");

dataOut.writeUTF("String from client");
System.out.println("Done 2");

dataOut.writeInt(2);
System.out.println("Done 3");

String string = dataIn.readUTF();
System.out.println("Done 4");

int number = dataIn.readInt();
System.out.println("Done 5");

socket.close();
System.out.println(string + " | " + number);

Exception in thread "main" java.lang.NoSuchFieldError: RAW_XML_FILE_HEADER

Hi everyone. I am new to Java and not even sure it can accomplish what I am trying to do. I have been asked to try to come up with a web based program that will create numbers in a sequential order....IE: 001, 002, 003.....upon every press of a button. I need these numbers to be able to be stored so that the next time someone else loads this up and presses the button, it will produce the next number in the sequence. It also has to work across many workstations and users. Is this even possible? Or should I look at another option? I thought Java might be the best option, seeing how easy it is to implement into HTML. Any help would be greatly appreciated.
