debugging xsl filters

Hi,

since I'm new to XSL(T) and want to write an export filter, I'd like to
debug the interaction with OOo. Issue

http://xml.openoffice.org/issues/show_bug.cgi?id=27616

states to enable it in javarc:


> If an XSL Transformation fails, the thrown exception can currently only be seen
> by setting up a line in the office installation file java.ini/javarc with
> '-DXSLTransformer.statsfile=<LOGFILEPATH>'.
> 

But in which section do I have to put it?
And does it really look like this:

-DXSLTransformer.statsfile=/home/marc/OOo-xslt.log

I assume it has to be added to some java command line or so ...

TIA,
Marc
