import java.sql.*;
import javax.swing.JOptionPane;
import java.io.File;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperReport;

import java.util.HashMap;
import java.util.Map;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperPrintManager;
import net.sf.jasperreports.engine.design.JRDesignQuery;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;

public class formlaporan extends javax.swing.JFrame {
kbayar kon=new kbayar();
JasperReport JasRep;
JasperPrint JasPri;
Map<String, Object> param = new HashMap<String, Object>();
JasperDesign JasDes;

public formlaporan() {
kon.SetKbayar();
initComponents();
}

private void bpelangganActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
try {

File reprt = new File("src/bayar/rep_pelanggan.jrxml");
JasDes = JRXmlLoader.load(reprt);
param.clear();
JasRep = JasperCompileManager.compileReport(JasDes);
JasPri = JasperFillManager.fillReport(JasRep, param, kon.conn);
JasperViewer.viewReport(JasPri,false);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage());
