Question

How can I create a barcode image in Java? I need something that will allow me to enter a number and produce the corresponding barcode image. Is there a free library availa

Answer 1

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 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.
