TableModelLocacao não é filho de DefaultTableModel. Verifique se o pai dela não é AbstractTableModel.

cara, desculpa sou meio leigo como faço isso

Marky.Vasconcelos

Voce não setou o TableModel da tabela.

TableModelLocacao modelo = //instancia como quiser
tabela = new JTable(modelo);

Depois disso voce conseguira fazer o cast.

cara agora eu dei o set. mas deu esse erro o que pode ser?
