[bamsThomas212]

I wanted to ask about the code that I have made if either variable or any of ... thank you ...
"incomparab le types: java.lang.strin g and int"

 if(StringUtils.isNullOrEmpty(txtIdPemesanan.getText())){
        JOptionPane.showMessageDialog(null, "ID pemesanan tidak boleh kosong", "Larangan", JOptionPane.ERROR_MESSAGE);
    }else{
        pemesanan = pemesananController.findPemesanan(txtIdPemesanan.getText());
        [B][U]if (pemesanan.getIdPemesanan()== 0)[/U][/B] {
            JOptionPane.showMessageDialog(null, "Data yang dicari tidak ada!");
        }else{
        txtIdMarketing.setText(pemesanan.getMarketingIdmarketing()+"");
        jDatePemesanan.setDate(pemesanan.getTanggal());
        txtIdCustomer.setText(pemesanan.getCustomerIdcustomer()+"");
        
        CustomerJpaController customerController = new CustomerJpaController(emf);
        Customer customer = customerController.findCustomer(pemesanan.getCustomerIdcustomer());
        txtNamaCustomer.setText(customer.getNmCustomer());
        
        DetilbarangJpaController detilBarangController = new DetilbarangJpaController(emf);
            javax.persistence.Query namedQuery = detilBarangController.getEntityManager().createNamedQuery("Detilbarang.findByPemesananIdPemesanan");
        namedQuery.setParameter("pemesananIdPemesanan", pemesanan.getIdPemesanan());
        List<Detilbarang> listDetilBarang = namedQuery.getResultList();
        DefaultTableModel model = (DefaultTableModel) tblDetilBarang.getModel();
        int i = 0;
        while (i < tblDetilBarang.getRowCount()){
            model.removeRow(i);

thanks for helpme...... :)

i guess you are comparing a string with integer value 0
if you want to compare a string then use,

pemesanan.getId Pemesanan() == null
