Conversion error

Question

I’m trying to update a schedule through Jtable. But when I try to update it gives an error

java.sql.Sqldataexception: data Exception: invalid Character value for cast

private class BtEditarListener implements ActionListener {

        public void actionPerformed(ActionEvent e) {
            int linhaSelecionada = -1;
            linhaSelecionada = tabela.getSelectedRow();
            if (linhaSelecionada >= 0) {
                int idContato = (Integer) tabela.getValueAt(linhaSelecionada, 0);
                AtualizarContato ic = new AtualizarContato(modelo, idContato, linhaSelecionada);
                ic.setVisible(true);
            } else {
                JOptionPane.showMessageDialog(null, "É necessário selecionar uma linha.");
            }
        }
    }

How do I get to carry out the conversation to update.

Can the error be caused by the bank account? Or the Java version? The computer uses Access and Java is in 1.6

Flávia Bruna, please post the stack trace of the error. The way you put it seems to be here the error:

int idContato = (Integer) tabela.getValueAt(linhaSelecionada, 0);

However, apparently there is nothing abnormal there since the method returns an Objetc and really needs a cast. So the idea would be to post the stack trace.
