E aqui s�o os m�todos que o erro aponta:

private void btnSalvarActionPerformed(java.awt.event.ActionEvent evt) {                                          
        //try {
            Connection con = Conexao.abrirConexao();
            ConsertoDAO cd = new ConsertoDAO(con);
            ConsertoBean cb = new ConsertoBean();
            
            cb.setNumProc(txtNumProc.getText());
            cb.setReclamante(txtReclamante.getText());
            cb.setReclamada(txtReclamada.getText());
            cb.setArquivo(txtArquivo.getText());
            
            JOptionPane.showMessageDialog(null, cd.cadastrarProcesso(cb));
            Conexao.fecharConexao(con);
        //}catch(Exception ex){
        //    JOptionPane.showMessageDialog(null, "Erro ao cadastrar.");
        //}
    }

public String cadastrarProcesso(ConsertoBean proc) {

        String sql = "insert into arquivo(num_proc, nome_reclamante, nome_reclamada, local_arquivo) values(?, ?, ?, ?)";

        try {
            
            PreparedStatement ps = getCon().prepareStatement(sql);

            ps.setString(1, proc.getNumProc());
            ps.setString(2, proc.getReclamante());
            ps.setString(3, proc.getReclamada());
            ps.setString(4, proc.getArquivo());

            if (ps.executeUpdate() > 0) {
                return "Cadastro realizado com sucesso.";
            } else {
                return "N�o foi poss�vel realizar o cadastro.";
            }

        } catch (SQLException ex) {
            return ex.getMessage();
        }

Se algu�m entender e conseguir me ajudar agrade�o bastante.
