Hi Fernando,

I would guess that you have an older version of FOP in your classpath. Older
versions expected "centered" instead of "center" and most of the other error
messages can be explained by this.

Further, if you are using Xalan 1.x, it doesn't output DOM2-compliant
namespaces, so the part you copied from Cocoon is wrong. In that case, if
you're copying code, you need to use the latest cocoon 1.8.x CVS code
(thanks Robin!) for that part. If you're using Xalan 2, then you're better
off copying from Cocoon 2's CVS (it's simpler). 

Please make these changes and let us know if it doesn't fix you up. Also
provide your classpath and the versions for everything in there (JDK, Xalan,
Xerces, etc.).
-Steve

Hi,

I'm a beginner in FOP and I download the fop-0_15_0-forBeginners.zip file.
Now I'm trying to build my first PDF. But I obtain severals warnings and
errors:

file to render: fop/docs/examples/fo/images.fo

I'm interesting in know why I have "WARNING: Unknown formatting object"


using renderer org.apache.fop.render.pdf.PDFRenderer
