JTextArea (kind of stupid)

ok ... I dont have my Java book here at work.... and I cant figure out why when I add a JTextArea and i write on it... is not multiline... how can I make it multiline???????

Also.... I have a little problem with GridLayouts...

Code:

---

                        JPanel pane=new JPanel();
                      pane.setLayout(new GridLayout(2,2));
                                           
                      pane.add(txt1);
                      pane.add(txt1);
                      pane.add(btn);
                     
                      setContentPane(pane);

I have 2 textareas and I button... i want the first TextArea to take the 2 rows in the first line... and the second textarea and the button each one on a cell the line of the button....

I know you have to add a parameter when you add the component.... right? how??

THANKS!! :)
