That should work, but you might want to try it this way instead:

  xsltproc --stringparam fop.extensions 1 \
    /usr/share/xml/docbook/stylesheet/nwalsh/fo/docbook.xsl \
    docbook-test-02.xml > docbook-test-02.fo

Then this:

  fop docbook-test-02.fo docbook-test-02.pdf

Which PDF viewers did you try?

That "ERROR" message does not really indicate a fatal error. FOP
will emit that message every time you run it with a DocBook doc.
But it will still generate a usable PDF in spite of it.

How much memory do you have on your machine? Perhaps FOP is
running out of memory.

I just tried on a Debian system with version 1:0.20.5-5 of the
"fop" package, and I got a usable PDF (could open in xpdf,
acroread, evince). You can check it here:

  http://docbook.sourceforge.net/outgoing/docbook-test-02.pdf

If you try calling xsltproc and fop as I've described above, and
it still doesn't work, I'm not sure what else to suggest. You
might try running FOP against some other .fo files and see if it
hangs on those. If you have fop-doc installed, you can find a
bunch of (gzipped) .fo files in:

  /usr/share/doc/fop-doc/examples/fo

Hope that helps,
