How to display String/text in a JFrame ?

Question

Hi,
I set up a simple browser and pinging a server (say localhost). Then under that server directory, I am looking for a file. Then, I use input or output stream to bounce the text back to browser to display out on the screen. It was successful.
But, just can't display out in a text area (say a frame or something).
The string coming back from server say called s (one line at a time using buffer).
public class VerySimpleBrowser extends JFrame {
public JTextArea t;
public VerySimpleBrowser() {
super ("VerySimpleBrowser");
Box b = Box.createHorizontalBox();
b.add(new JScrollPane(t));
Container c = getContentPane();
c.add(b);
setSize(850,600);
show();
void static main ...
while ((s=fromServer.readLine()) != null)
//System.out.println(s);
t.setText(s);
Then, I got NullpointException error ?! The frame poped out ok, but nothing was written to it.
Thanks for help.

To save you from pulling all your hair out, here is what you've to do:
String out=""
while ((s=fromServer.readLine()) != null) {
   out+=s;
   t.setText(out);
.....V.V.
