Hi,<\/p>\n

In one of my project i needed to generate EAN-8 standard bar-code for identifying the various products. I searched for various libraries available for generating bar-code and found a library to do so. The library i used for generating the bar-code is Barcode4J.
\nYou can download it from here<\/a><\/p>\n

\nBarcode4J is a flexible generator for barcodes written in Java. It’s free, available under the Apache License, version 2.0<\/a>.
\nThe bar-code generated with the help of of this library uses eight digit number hence EAN-8.<\/p>\n

To generate bar-code image from this library is quite simple. Just put the barcode4j.jar<\/strong> in the lib folder of the application.<\/p>\n

\r\n\r\n<\/pre>\n
Code to generate image is:-<\/p>\n
[java]
\npublic File generateBarcode(Long codeDigits){
\ntry {
\n      \/\/’codeDigits’ is the code for which we want to generate bar-code image
\n     EAN8Bean bean = new EAN8Bean();
\n     final int dpi = 150;
\n     bean.setModuleWidth(UnitConv.in2mm(1.0f \/ dpi));
\n     bean.setFontSize(2.0)
\n     bean.doQuietZone(true)
\n     File outputFile = new File(filepath) \/\/ existing file in the file system
\n     OutputStream out = new FileOutputStream(outputFile)<\/p>\n
     \/\/ class to convert provided image into barcode image
\n     BitmapCanvasProvider canvas = new BitmapCanvasProvider(out, "image\/jpeg", dpi,   BufferedImage.TYPE_BYTE_BINARY, false, 0)
\n     bean.generateBarcode(canvas, codeDigits)
\n     canvas.finish()
\n     return outputFile
\n}<\/p>\n
[\/java]<\/p>\n
So, here it takes a file from the file system and convert it into the required barcode image. Now, the user can simply display this image on the items.
\n
\nIn my case, i needed to generate a bar-code image for each product, so i create new file for every item, and stored it on the file system with unique name.<\/p>\n
\nThis works in my case.
\nHope it helps<\/p>\n
\r\n\r\n<\/pre>\n
Cheers..!!!
