Paloma,
What I did to resolve this problem was to set the configuration at runtime as follows:
Configuration.put("version", "FOP 0.20.5");
Configuration.put("stream-filter-list", "flate");
Configuration.put("stream-filter-list", "ascii-85");
List<String> streamFilterList = new ArrayList<String>();
streamFilterList.add("flate");
streamFilterList.add("ascii-85");
Configuration.put("stream-filter-list", streamFilterList, Configuration.PDF);
Hope this helps.
Paul

Hi all,
A few days ago I realized that the pdf resource is not working. I have
tried to find out what's wrong with it but I haven't succeeded so far.
This is what I know:
*The changes made to this resource has been related to replacing Path to
String (See below for a diff between the original and the current version)
*The file is actually created, but I get the following error message
when I try to open it
"The file was damaged and could not be repaired"
*The problem seems to lie in the transformation since the resulting file
contents are:
---------------------------------------
%PDF-1.3
%ª«¬
4 0 obj
<< /Type /Info
/Producer (null) >>
endobj
5 0 obj
<< /Length 94 /Filter /Flat
----------------------------------------------------
*However, if I run fop 0.20.5 from the command line the transformation
works:
--------------------------------------------
%PDF-1.3
%ª«¬
4 0 obj
<< /Type /Info
/Producer (FOP 0.20.5) >>
endobj
5 0 obj
<< /Length 120 /Filter [ /ASCII85Decode /FlateDecode ]
>>
stream
[....]
----------------------------------------------
Therefore I guess the problem is the java code performing the
transformation. However, since that part of the code has not been
changed significantly I can't see why it shouldn't work. Any hints?
Anyway, I'll keep on looking into it and let you know about my findings.
Regards,
Paloma
