U R not trapping any action Event where is the objet.getSource() , in ur actionPerformed.

modify the code in ur acrtionPerformed method , and it will work fine

public void actionPerformed(ActionEvent thisEvent)
{
Object obj = thisEvent.getSource();
if (obj.equals(pressMe))
{

String name = answer.getText();
Label personalGreeting = new Label("");
personalGreeting.setText("Hi " + name);
add(personalGreeting);
}

Jdoit,

Thanks it worked. But I would not like the originaly typed text to remain when I enter a new text.
Suppose ,In the text box I type TOM and click the press button it writes out HiTom. Now When I next enter Peter in the text box and click it writes out Hi peter and the Hi Tom still remains.How Do i get rid of the Hi Tom .
Also Could you please tell me a good web site for learning to write applets which givs lot of explanations and gives a variety of examples.
