Running FOP with a DTD catalog

Hello everybody,


I am trying to process files with a DTD reference from the (Windows) command line.
C:\[...]\fop-2.2\fop.bat -xml "C:\Users\[...]\inputfile.xml" -xsl transformation.xslt -pdf outputfile.pdf -catalog

In order to do so, I use the -catalog option for FOP(2.2). I have a CatalogManager.properties in my running folder (using verbose=4), pointing to the catalog file.
When running FOP, output reports the mapping to the correct DTD entries, so I am sure that catalog is being read.

After that, FOP errors out:

SEVERE: Exception

Indeed the (public) DTD is not in the same folder, but the catalog file which points to the location of the DTD's should solve that. As you can see from the error, I am currently testing this with Saxon.
When running Saxon on its own to isolate the xml->fo part, I can make the catalog work as well by running:
"C:\[..]\java.exe" -cp C:\[...]\saxon9he.jar;C:\[...]\resolver.jar -Dxml.catalog.files="C:\[...]\CatalogueFile.xml" net.sf.saxon.Transform -r:org.apache.xml.resolver.tools.CatalogResolver -x:org.apache.xml.resolver.tools.ResolvingXMLReader -y:org.apache.xml.resolver.tools.ResolvingXMLReader -xsl:inputfile.xml -s:transformation.xslt -o:outputfile.fo

I have the impression that fop is not forwarding catalog setting to Saxon... Can any of you make some suggestions on how to set this up or what to test?


Thanks,
