Specifically, the manipulatePdf function:
PdfDictionary action = field.getAsDict(PdfName.A);
PdfDictionary f = action.getAsDict(PdfName.F);
f.put(PdfName.F, new
PdfString("http://itextpdf.com:8080/book/request";);
Your code is presumably looping through every object in the PDF, looking
for one that contains the string "/Filespec". That could work, but you
don't know if the file specification is its own object, or part of
something else. File speicifcation dictionaries are not required to be
top level objects, so just because you see /FileSpec doesn't mean you
know now to it out of your "obj".
You say this is a link in a PDF collection. In THIS PARTICULAR CASE, it
sounds like you can safely use that technique. As soon as your PDFs
start coming from different sources, or the file isn't part of a
collection, all bets are off.
To generalize your code a little more, I suggest the following... You'll
have to forgive my Java, I no speaky VB.net.
if (obj.isDict()) {
PdfDictionary dict = (PdfDictionary) obj;
if (dict.getType() == PdfName.FILESPEC) {
PdfString oldSpec = dict.getAsString(PdfName.F);
String specStr = oldSpec.toString();
String newSpecStr = modifySpecStrSomehow(specStr);
dict.put(PdfName.F, new PdfString( newSpecStr );
}
}

Hi,
I would like to know if is possible to modify pdf object
and re-save the pdf with changes.
This is an example that shows how to replace an URL:

If you want to know more about the structure and the content of
the objects, you need to read ISO-32000-1.
