I use  barbeque   it s great  and supports a very wide range of different barcode formats  See if you like  its API    Sample API   public static Barcode createCode128 java lang String nbsp data                               throws BarcodeException     Creates a Code 128 barcode that   dynamically switches between character   sets  to give the smallest possible   encoding  This will encode  all   numeric characters  upper and lower   case alpha characters and control   characters  from the standard ASCII   character set  The size of the barcode   created will be the  smallest possible   for the given data  and use of this    optimal  encoding will  generally   give smaller barcodes than any of the   other 3  vanilla  encodings

iText is a great Java PDF library  They also have an API for creating barcodes  You don t need to be creating a PDF to use it   This page has the details on creating barcodes  Here is an example from that site   BarcodeEAN codeEAN   new BarcodeEAN    codeEAN setCodeType codeEAN EAN13   codeEAN setCode  9780201615883    Image imageEAN   codeEAN createImageWithBarcode cb  null  null     The biggest thing you will need to determine is what type of barcode you need  There are many different barcode formats and iText does support a lot of them  You will need to know what format you need before you can determine if this API will work for you
