JLabel Word Wrap

try the following:

[code]
JLabel label = new JLabel("<html><table><td width='\" + width + ""\>Some very very very very very long text </td></table></html>")
[/code]
where width is width you want label to fit on. i used parent panel width - borders width.

Use html tags and set preferred size to 1x1. It will automatically resize

 JLabel label = new JLabel("<html>your text here</html>");
