Please note, the resulting PDF document does not look very pretty. This is because the XSL stylesheet is very basic and does not really apply much FO formatting tags/attributes. It would be very easy to modify the XSL to include images, bold, grey background cells etc.. but this is best left for the FOP documentation to describe.

To support the execution of the User service level test, we need another helper file. This file (attached at the end) is called FOPHelper.java and lives in src/service/**/fop.

Add the following imports and method to UserManagerTest.java:

Now execute ant test-service. The testGeneratePDF method will execute and generate the 3 files involved in the PDF generation
process. user.xml, user.fo and user.pdf (all three attached at the end of this tutorial).
You should see output:
