Matthias,
you can upgrade to 0.9x versions of FOP if you implement a cocoon
serializer by your own, as i did for my own project. I'ver attached my
pretty simple java code, that might be improved if needed ;-). Just
provide this to the cocoon classpath, replace the fop jars with current
0.9x builds and add the serializer inside the cocoon "sitemap.xmap":
<map:serializer name="fo2pdf" mime-type="application/pdf"
src="CocoonFOPSerializer"> <set-content-length>false</set-content-length>
</map:serializer>
HTH, Arne

Thx for your experiences. I can't upgrade to 0.93 since it's not supported by
the latest stable apache cocoon version. i desire the upcoming version 2.2
since months ;-)
Thx Louis for the code snippet. i try to figure out why i have such a large
increasement. I'll let you kow,
greetings matthias
