Hi,
I'm generating epub from Docbook via Apache Ant and I'm getting the
following error during the validation with Epubcheck.
[java] Epubcheck Version 3.0ERROR:
/home/vogella/workspace/docu/de.vogella.publishing/../output/epub/book.epub:
Extra field length for first filename must be 0, but was 20
Any suggestion what might be causing the error.
I generate the epub via the following snippet (see below).
Thanks for any help, Lars
