Today I decided to do a clean install on Ubuntu 9. And a good thing I did, since my customer had trouble with making Apache FOP, one of the programs I use in the project, work with the Barcode4J extension. Note that if you want to write your own Java programs you might want to install the Java Development Kit instead, i. Press tab to navigate to the Ok button and press enter if you want to agree with the license.

In the next "window", press the left arrow key to select the Yes button and press Enter, and the installation of the Java runtime environment should continue.

Now the command java -version should report a message identical or similar to: java version "1. FOPException: No input file specified followed by a stack trace. On top of that, barcodes can be rotated as well. After the download has finished, move the zip file to a directory you want it installed in. This can be a newly created hidden directory in your home directory, for example.

Extract the file: unzip barcode4j The jar files are located inside the build sub directory of barcode4j In Ubuntu 9. However, on Ubuntu 8. Something I and my customer bumped into today, since I develop on Ubuntu 8.

Do not accidentally use the full path of barcode4j-fop-ext IncompatibleClassChangeError: Implementing class Next, change your working directory to the xsl-fo directory which is located in the examples sub directory of barcode4j Open this file and verify it has several generated barcodes in it; you can open this PDF file from the command line as follows: xdg-open test.

This is most likely caused by the Barcode4J extension not being available in the class path. If you do get the barcodes in the PDF file you might want to add the export command to your. The Document Viewer notices that the pdf file has changed, and reloads it. This is very handy when tweaking XML files. Saxon-B was installed using: sudo apt-get install libsaxonb-java After the installation has completed, entering saxonb-xslt on the command line should report version information, for example "Saxon 9.

Putting it all together Below follow two files which can be used to create a simple PDF file with a barcode and, bonus, a "watermark" image; an image that is used as a background on top of which the text and the barcode are rendered.

The image itself is not available for download, so you have to add an alternative image named watermark. This file can be converted to an XML file containing formatting objects using Saxon-B and the stylesheet that follows after this code. The stylesheet consists roughly of four parts: a part defining the region body, including specifying a background image watermark , a very small part selecting the value of the heading element and putting it in a block element with a font size of 18 point and a margin of 0.



Get a TrueType barcode font for the barcode type you need. Note that in the above XSL example the margins of the fo: You can check this using:. As a first try I suggest you to use the fop. Ideally, the barcodes fpp be generated from inside the template, rather than calling another program to generate them and then have the template try to find them as PNGs or some other image format. This will create a file named test. Save the XML stylesheet code that follows below to a file named hello-barcode.


Instructions for the Apache FOP extension

Setting up the barcode extension with Apache FOP 0. Alternatively, you can use the combined JAR: barcode4j-fop-ext-complete. Alternatively, you can use the combined JAR: barcode4j-fop-ext Important: When you use FOP 0. The version from FOP 0. The attribute is optional and if set must be one of the following values: 0, 90, , , , , Some characters like RS record separator and GS group separator are sometimes required for certain applications but these characters are not valid XML characters and cannot be encoded.


Barcode generation with FOP 1.1

Barcode generation templates can be called directly from within XSL stylesheets with no need for special barcode fonts or third-party image-drawing software. Compared to other methods of producing bar codes in XSL FO, this technique has obvious advantages: printed output is the sharpest possible since it is a vector graphics; image size is reduced; every aspect of the barcode pattern can be controlled - stroke widths, colors, lengths, etc. The links below lead to examples and XSLT stylesheets for several popular barcode types. Each stylesheet exports a named template that takes a string as input and creates an SVG image of the barcode that represents that string. Additional parameters specify details of code format and presentation.
