RE: Unknown formatting object (Solution Update)

["Willis, Matthew" <mw...@jhancock.com>]

Hi,

J. Pietschmann and Adam Shelley were kind enough to point me in the correct
direction for solving my original problem.  Thanks go to them for their
time.  I'm documenting the solution here so it'll be available in the
email-list archive.

...here's the original problem statement...

I'm getting the following exception: 

WARNING: Unknown formatting object
http://www.w3.org/1999/XSL/Transform^stylesheet 
org.apache.fop.apps.FOPException 

when running the following code snippet to set up an embedded FOP: 

Driver fopDriver = new Driver(new InputSource(XSL_FO_FILE_PATH), new
FileOutputStream(OBI_PDF_PO_FILE_PATH)); 
fopDriver.setRenderer(Driver.RENDER_PDF); 
fopDriver.run(); 

While researching the problem, I found in one of the FOP FAQ's that
receiving something like this error means that I need to check that the xsl
namespace is set to http://www.w3.org/1999/XSL/Transform.  I've
double-checked this and it appears to be set correctly (see below).

<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:fo="http://www.w3.org/1999/XSL/Format"> 

Anyone have any clues? 

Here are the versions I'm using for the various jars: 

xalan 2.0.0 
xerces 1.2.3 
fop 0.18 DEV 

Running fop at the command line works fine with these.  Running it embedded
on the other hand...



...And here's what was done to fix the problem:

1)  After reading the documentation that Adam and J. recommended, I modified
the code I was using to embed FOP.  Now I'm doing this:

Driver driver = new Driver();
driver.setRenderer(Driver.RENDER_PDF);

InputHandler inputHandler = new XSLTInputHandler(new
File(OBI_XML_PO_FILE_PATH), new File(XSL_FO_FILE_PATH));
XMLReader parser = inputHandler.getParser();

driver.setOutputStream(new FileOutputStream(OBI_PDF_PO_FILE_PATH));
driver.render(parser, inputHandler.getInputSource());

2)  This generated the exact same error when using FOP-0.18.1.  However,
once I switched to FOP-0.20.4, the following FOPException was generated:

'master-reference' for 'fo:page-sequence' matches no 'simple-page-master' or
'page-sequence-master'

3)  Upon reading the FOP-0.20.4 Release Notes, this was resolved by changing
the 'master-name' property in my XSL document to 'master-reference'.

With these mods, everything works quite well now.

Thanks,
Matt

You are feeding the style sheet as input to the formatter. This can't work,
the formatter will only take FO documents, which is something different. If
you want to transform some input XML with the style sheet and have the
formatter work on the result of the transformation, see
   http://xml.apache.org/fop/embedding.html#servlet-transform

That's darn old, you should upgrade. The code example above probably won't
work with this old FOP release.
