Everyone loves a well-designed Web page, but I hope you never tried to print one and found out that it resulted in a big mess and maybe some unhappy users. There are many technologies that you can use to solve this problem, but the majority of them require spending some money and time.

Today we are going to talk about the FOP (http://xml.apache.org/fop) Formatting Objects Processor. You can download the code from the Web site free of charge, but it requires some time to learn how to use it and how to create good solutions. Essentially, FOP is based on the W3C recommendation http://www.w3.org/TR/2001/REC-xsl-20011015/.

The best way to learn how to use FOP is to create a sample. For example, let's imagine that we need to generate a PDF file with the price list of the ACME Corporation. It should look like the following:

First of all, we need to start our document as follows:

This helps us to define the correct namespace (http://www.w3.org/TR/REC-xml-names/) that we need to use.

After that, we will need to define the size of the output page that we want to use.

With this information available, we just create a standard, letter-sized page. After this, we need to create a section with the actual layout of the document that we need to generate.

This statement will match with the layout defined above and it will set the page number to 1. To print out any message, we need to define . Implementing FOP

This block will generate a 24pt line with blue background and white letters, centered, and with the title Implementing FOP.

Now, let's include a table with the products' numbers, descriptions, and prices. This is the header of the table: Product Number Description Price

One important issue is that we need to include a prefixed size of the column. Right now, FOP does not allow you to define automatic layouts.

We use the same approach as HTML by using . Here is how it looks after we include the table. ***************************sample.fo ********************************* ACME Corporation Product Number Description Price 12345 Rocket $250.00 67890 TNT
