Always state the FOP and JDK version you're using.
You can run Ant using the "-d" or "-v" parameters and then you should
get stack traces.

Hi,
I get a NullPointerException when calling Fop from my Ant script:
<macrodef name="pdf">
<attribute name="filename" />
<sequential>
<ant antfile="${docbook.xsl.home}/scripts/build.xml"
target="build.fo">
<property name="file.name" value="@{filename}"
/>
<property name="target.dir" value="pdf" />
</ant>
<fop fofile="pdf/@{filename}.fo" outfile="pdf/@{filename}.pdf"
format="application/pdf" messagelevel="debug" />
</sequential>
</macrodef>
<target name="generate">
<pdf filename="TechReport" />
</target>
No stacktrace ;-(
The .fo file is attached.
Any ideas?
Cheers
