                                                  1. Introduction  

                                                  The J4L FO Designer is a graphical tool for designing XSL-FO documents. XSL-FO is a language for formatting XML data and one of the most popular uses is for converting "technical" XML files to user friendly PDF files.

                                                  This tool uses the Apache FOP package for executing the XSL-FO documents and therefore it is specially suitable for Java environments.

                                                  The FO Designer will help you in the task of creating PDF files from XML files. There is no need for you to learn the XSL-FO language. Even if you are familiar with the XSL-FO language, the designer provides you with a user friendly graphical tool for increased productivity

                                                  Furthermore the designer provides an integrated environment for:

                                                  • Designing the PDF files in a WYSIWYG manner.
                                                  • Loading and modifying XML files for the testing.
                                                  • Running tests and checking the output with one click.

                                                  When working with the designer you will be handling up to 6 different files:

                                                  1. The input XML file (also called XML document in this guide) which needs to be converted to PDF
                                                  2. schema file, with extension *.xsd (optional) which defines the structure of the XML document. In the schema file you have a list of all possible elements contained in the input XML document. So, from the schema you can select fields to be placed on the PDF file.
                                                  3. The XRE file (also called document template or report in this guide) which stores the layout of the desired output, this is what you see in the designer and is used at design time only.
                                                  4. The document. The XSL-FO output is generated by the designer and used at runtime by Apache FOP to convert your XML file to PDF.
                                                  5. FO output ( FO tab) which is the result of applying the text XML file to the XSL- FO document..
                                                  6. The output PDF file.
