Hello, I have a problem with metadada part of PDF created by Apache FOP 0.95 (using Sun Java SE 1.6.0_10 on MS Windows 2000). Although resulted PDF looks OK in Acrobat Reader, I am not able to process resulted PDF using iText 2.1.3. It throws Exception shown below. After several e-mails among iText developers (and me), it looks like even if I do not specify any metadata in FO, FOP 0.95 produces PDF with compressed not valid XML metadata section according to iText developers. If I specify metadata according to Your example at
http://xmlgraphics.apache.org/fop/0.95/metadata.html#xmp-example there is the same Exception. So, could You, please, verify, if the problem is really caused by FOP and if yes, to repait it? Thank You very much in advance.
