Barcode generation in java

Question

I am making an application to generate barcodes, but it does not give me the barcode: the application returns the text that I have provided. My code is:

Code39 code39=new Code39();
String outputStr=code39.encode("12345678", 1);
String humanTextStr=code39.getHumanText();
jLabel1.setText(outputStr);
jLabel1.setFont(new java.awt.Font("CCode39_S3",java.awt.Font.PLAIN,24));

Please can anyone tell me why this happens?

I want the Text I have provided is set JLabel1 as in barcode format But it gives me output is as:*12345678-* — Jayashri, Jul 15 '12 at 04:00

Your application is returning a text because you have told it to get the text not the bar-code.

Try the following code:

a=jTextField24.getText();      
Code39 barcode=new Code39();      
barcode.setData(a);      
ImageIcon icon = new ImageIcon(barcode.drawBarcode());          
jLabel34.setIcon(icon);

Try using open source libraries for generating barcodes in java. For e.g., iText or http://barbecue.sourceforge.net/

Please refer to this link as well BarCode Image Generator in Java
