The answer lies within the code to "execute". This part in particular:
PdfDictionary names = catalog.getAsDict(PdfName.NAMES);
if (names != null) {
PdfDictionary embFiles = names.getAsDict(new
PdfName("EmbeddedFiles"));
if (embFiles != null) {
HashMap< String, PdfObject > embMap =
PdfNameTree.readTree(embFiles);
for (Iterator< PdfObject > i = embMap.values().iterator();
i.hasNext()){
PdfDictionary filespec = (PdfDictionary) PdfReader
.getPdfObject(i.next());
unpackFile(reader, filespec, outPath);
}
}
}
In Plain English, the dictionary stored in the EmbeddedFiles key is a
bunch of name/value pairs where the values are (I believe)
PdfIndirectReferences to file specification dictionaries. The
unpackFile function expects a single fileSpec dictionary. << /Type
/FileSpec ... >>
A more helpful error message from unpackFile might be nice rather than
simply returning. Something like throw new DocumentException("That
dictionary isn't of /Type /FileSpec"). At least then you would have
known you weren't passing in the correct dictionary. That may not have
helped you, but then again...
OTOH, I didn't think the toolbox code was supported anymore, so it
surprises me to see generics used in there. Live & learn.
