JTabel + Model / interaktiv Reihe einfügen

[acky]

hi,

ich schaff es partout nicht, eine reihe in ein JTable einzufügen. auch

DefaultTableModel model = (DefaultTableModel)table.getModel();
model.addRow( string[] );

hat bei mir leider nicht funktioniert. lies sich zwar fehlerlos kompilieren, doch
beim ausführen tat eine "classCastException" auf.

wäre dankbar, wenn mir da jemand weiterhelfen könnten - bitte
keine (wichtigen) details verschweigen . (da ich durch die technik
offenkundig noch nicht wirklich durchblicke!)

danke,
acky
