Maybe not, but this forum is for Java technical questions, as described here[^].

XMPP is an protocol and many implementation of it is based on java

But your question is not about Java, it is about learning XMPP, and I already provided you a Google search that returns lots of links. It is now up to you to go and study some of them.

This site does not provide code to order; you need to do your own research.

Look at the file LZW.java available at Professor Sedgewick's site[^].

I've trying CardLayout prog. but the program is not displaying the buttons at all. I tried a lot but could not find out the error. If you could look into this code and tell me where I am going wrong I would be grateful to you.

The code is as follows:

import java.awt.*;
import java.awt.event.*;

class CardLayoutTry implements ActionListener
{
Frame frm;
Button window,linux;
Checkbox chkWin7,chkWin8,chkWinXP,chkWinVis;
Checkbox chkUbuntu,chkMint,chkFedora,chkRedHat;
Panel deck, panWin,panLin;
CardLayout cardLO;
Label lblWin,lblLin;

CardLayoutTry()
{
cardLO=new CardLayout();
frm=new Frame("Operating System");

frm.addWindowListener(new WindowAdapter(){
@Override
public void windowClosing(WindowEvent we)
{
frm.setVisible(false);
System.exit(0);
}});

frm.setVisible(true);
frm.setSize(300,300);

deck=new Panel(); // main panel
deck.setLayout(cardLO); // setting the layout

panWin=new Panel();
panLin=new Panel();

window=new Button("Windows");
frm.add(window);
window.addActionListener(this);

linux=new Button("Linux");
frm.add(linux);
linux.addActionListener(this);

// ADDING LINUX DETAILS

lblLin=new Label("LINUX OPERATING SYSTEM",Label.CENTER);
panLin.add(lblLin);
chkUbuntu=new Checkbox("Ubuntu",true,null);
chkMint=new Checkbox("Mint");
chkFedora=new Checkbox("Fedora");
chkRedHat=new Checkbox("Red Hat");

panLin.add(chkUbuntu);
panLin.add(chkMint);
panLin.add(chkFedora);
panLin.add(chkRedHat);

deck.add(panLin,"LinuxPanel");

// ADDING WINDOWS DETAILS

lblLin=new Label("WINDOWS OPERATING SYSTEM",Label.CENTER);
panLin.add(lblLin);
chkWin8=new Checkbox("Windows 8",true,null);
chkWin7=new Checkbox("Windows 7");
chkWinXP=new Checkbox("Windows XP");
chkWinVis=new Checkbox("Windows Vista");

panWin.add(chkWin8);
panWin.add(chkWin7);
panWin.add(chkWinVis);
panWin.add(chkWinXP);

deck.add(panWin,"WindowsPanel");

frm.add(deck);

frm.addMouseListener(new MouseAdapter(){
@Override
public void mousePressed(MouseEvent me)
{
cardLO.next(deck);
}
});

}

@Override
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==window)
cardLO.show(deck,"WindowsPanel");

else if(e.getSource()==linux)
cardLO.show(deck, "LinuxPanel");
}

public static void main(String args[])
{
new CardLayoutTry();
}
}

This should come at the end

Java

frm.setSize(300,300);
frm.setVisible(true);

Respected Sir/Madam

1) Purpose of Looping statement? when we use looping? clearly difference between for, while and Do while loop with real time example

See The Java Tutorials[^].

Use the best guess

Look at the PPT and code associated with Chapter 4 - Statement Forms, in the website of the book The Art and Science of Java[^] to understand loops. First, understand the "for" loop and master that; then explore "while" and "do".

Create a project and press Run. We cannot tell from this exactly what your problem is. Please try and explain in full detail.

That is what I asked you to do. Your original question gives no clue as to your problem.

Unless it is a sock puppet, he replied to you instead of replying to the OP.

Yeah, spotted that after I posted my comment. However, it doesn't add much to what I already asked so, nuff's 'ead.

Sorry but that does not make much sense. Please show the lines of code where the error occurs and the exact message that you see.

The superscript denote that its a java application. Except this what is your problem?

Hi All,

I am looking forward to actually configure a logger that should be created for different IDs.

My application is very huge and there are nearly 20 users accessing the application at a time so when they get any exceptions it is becoming very difficult to check in the log what actually went wrong.

So i want to create a logger in such a way that its generates the log on the ids (unique) that i provide.( i.e i mean separate logger for each ID)

Could anyone help me how this can be achieved .

Thanks

A better way would be to have a single logger that writes the messages, and adds the id and a dte and time to each message.
