If your question boils down to how to figure out if today is Monday, try this:

  
GregorianCalendar now = new GregorianCalendar();
int dow = now.get(GregorianCalendar.DAY_OF_WEEK);
if (dow == GregorianCalendar.MONDAY)
{
    updateWebSite();
}   

On the other hand, if you're asking how to update your website, that depends a lot on your website!
And before you ask, yes, in fact, the Gregorian Calendar is named after me.

String dateString = new java.text.SimpleDateFormat("E dd/MM/yy").format(new java.util.Date())

Today dateString would equal "Thu 20/02/03".

thanks guys
but when a person enters that page ,the next week
it should dynamically change it date..
think u guys got what i said..
the date should be changing every week dynamically.

[senthil sen]

the next week it should display like this
date day
08/02/03 monday
09/02/02 tuesday

it goes like this till sunday....
this should repeat dynamically every week

hi,
well any answers for this its really important and urgent to me guys.....

senthil,
Why do you want to use Java to do this? A simple web page could become complicated this way. Why don't you just use JavaScript to do it? No Java involved.
I think the JavaScript for that is just:
today = new Date();

thanks cindy,
well if we use the code

Date dt = new Date()
we would get the current date only,.
but what i need is if a user enter a page that page should show the current week
i.e
days and its date...
and this should change dynamically every week,when the user clicks the same page...

This code would get you the Monday of the current week ( disclaimer: code is completely untested )

public class MyGregorianCalendar extends GregorianCalendar
{
   public GregorianCalendar getMondayInWeek()
   {
      GregorianCalendar gcal = new GregorianCalendar();
      gcal.setTime( super.getTime() );
      switch ( gcal.get( Calendar.DAY_OF_WEEK ) )
      {        
         case Calendar.MONDAY:
            break;
         case Calendar.TUESDAY:
            gcal.add( Calendar.DATE, -1 );
            break;
         case Calendar.WEDNESDAY:
            gcal.add( Calendar.DATE, -2 );
            break;
         case Calendar.THURSDAY:
            gcal.add( Calendar.DATE, -3 );
            break;
         case Calendar.FRIDAY:
            gcal.add( Calendar.DATE, -4 );
            break;
         case Calendar.SATURDAY:
            gcal.add( Calendar.DATE, -5 );
            break;
         case Calendar.SUNDAY:
            gcal.add( Calendar.DATE, -6 );
            break;
         default:
            throw new IllegalArgumentException();
            break;
       }
       return gcal;
  }
}

just format the result using a SimpleDateFormat:

SimpleDateFormat formatter = new SimpleDateFormat( "dd/MM/yy" );
MyGregorianCalendar myCal = new MyGregorianCalendar();
System.out.println( formatter.format( myCal.getMondayInWeek() ) );

You get the idea,
