Generating PDF having barcode of a String (i.e. SKU), using open source APIs.

The acceptance criterion is that the generated bar-code should be able to be scanned by using any bar code scanner.

To generate Barcode, I have used “ Zxing “ API. The used jars used in the below example are: core-2.2.jar, javase.jar.

To generate PDF, I have used PDFBox  API. In this example I have used the following jars: pdfbox-1.8.10.jar, pdfbox-app-1.8.10.jar.

The above mentioned jar can be found at below link:

In the below example I am creating a PDF file having two pages and on each page there are two different barcode.

Here is the code:
