Do you use the LWUIT library? Then you should add the LWUIT tag. — Meier, Nov 17 '13 at 23:02

To make TextArea text scrollable, you must use a Scroll Pane.

You would need to do something like

JScrollPane scrollPane = new JScrollPane(textarea);

See more on JScrollPanes at http://docs.oracle.com/javase/7/docs/api/javax/swing/JScrollPane.html
