[oXygen-user] Configuring OT's FOP To Render MathML

[Oxygen XML Editor Support]

Hi Eliot,

The jar files that you added in the pdf2/fop/lib dir are not 
automatically loaded by the ANT process started from command line. I 
think that is true also for the PDF generation step (the FO -> PDF 
transformation) performed by FOP, regardless how the transformation was 
started. The JEuclid jar files have to be added to the classpath and 
that is what the -lib parameters do in the Oxygen command that runs the 
DITA transformation in the Oxygen application.

FOP delegates MathML processing to JEuclid (which is a FOP plugin) if it 
finds it in the classpath. If FOP does not find a FOP plugin for the 
MathML content you get the error about unrecognized MathML markup. 
JEuclid can handle inline MathML markup in the FO document exactly as 
you have it (inside <fo:instream-foreign-object> elements) so you should 
just add the two JEuclid jar files explicitly to the ANT classpath, for 
example as -lib parameters to the Java command that starts the ANT process.


Best regards,
Sorin
