Java Programming

Hi All,

I got problem with my barcode.
I have created report using iReport 0.5.0 this can work fine with viewer on iReport.
But when I call report from java program with jasperReport 0.6.7 I got the error:

Error evaluating expression : image_1
Source text : it.businesslogic.ireport.barcode.BcImage.getBarcodeImage(12,$P{p_noreg},false,false)

this is my simple code:

import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.view.JRViewer;
import net.sf.jasperreports.view.JasperViewer;
import java.util.HashMap;
import java.sql.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
import java.awt.*;

public class myReport {
    public myReport() {
        
        Connection con =null;
        String URL ="jdbc:postgresql://192.168.0.9:5432/SGHS";
        String user ="postgres";
        String pass ="hi1924";
        try{
            Class.forName("org.postgresql.Driver");        
            con=DriverManager.getConnection(URL,user,pass);
        } catch(ClassNotFoundException ce) {}
        catch(SQLException se) {}
	HashMap reportParam = null;
    	reportParam.put("p_noreg","050625001011");
	try{
    		JasperPrint print = JasperFillManager.fillReport("/root/jas/label.jasper", reportParam , con);
    		JasperViewer.viewReport(print);
	} catch(JRException je){System.out.println(je.getMessage());}
    }
    
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new myReport();
            }
        });
    }
    
    
}
