Can anyone help or tell me how to get more info out of FOP? (ie. some
DEBUG trace?) or even how to get hold of the generated FO file?
Thanks

Do the following: Instead of piping the result of the XSL transformation
through to FOP with the following line:
Result res = new SAXResult(driver.getContentHandler());
...simply serialize the resulting XSL-FO document to a file:
Result res = new StreamResult(new File("C:/Temp/debug.fo"));
Check if the FO file looks right and runs smoothly through FOP.
To debug the whole thing outside of your application you might want to
consider writing the early XML to a file. In this case your code would
look like in [1]. Note the identity transformer instead of an XSL
transformation. In this case you'd have a Result like this:
Result res = new StreamResult(new File("C:/Temp/debug.xml"));
Once you have the XML from your application, you can use xalan.bat, fop.bat
and your stylesheet to debug everything. Once your stylesheet is fixed
you can run the integrated code again that does the full functionality.
The key is to break down the whole process into it parts (creating XML
from your application, transforming using XSLT and formatting using FOP).

This is a problem with your XML/XSLT

Note, that the element being matched differs from the comment. However, this
may not be the cause of the problem. Most likely cause is several occurrences
of element incident in your source XML, resulting in several root elements.
To determine where mistake is you should generate XSL-FO file by running
xalan.bat (in FOP distribution) from command line.
