Hi,
Thsi is my problem:
I have create a pdf my adobe livecycle and I put it in a specific
folder. I have build the function
"copiaFileParam(String nomeFile,String pathSorge,String pathDest,String
new_nomeFile, String cordX,String cordY)"
That create a copy of my pdf setting a value field with the parameter
cordX,cordY.
//I compose the name of the source pdf and the pdf of destination
inputFile = pathS + nomeFile;
outputFile = pathD + new_nomeFile;
//get a pdf reader
pdfr = new PdfReader(inputFile);
Node n = pdfr.getAcroFields().getXfa().getDatasetsNode();
Xml2SomDatasets som = new Xml2SomDatasets(n);
Set<HashMap> map= som.getName2Node().keySet();
XfaForm xfa = pdfr.getAcroFields().getXfa();
try
{
//Create a new pdf
stamper = new PdfStamper(pdfr, new FileOutputStream(outputFile));
xfaForm = new XfaForm(stamper.getReader());
//Setting the value
GestioneSchede.setValore(map,"ppc_cordx",xfaForm,cordX);
GestioneSchede.setValore(map,"ppc_cordy",xfaForm,cordY);
//Set the datasetsSom
stamper.getAcroFields().getXfa().setDatasetsSom(som);
//Set xfa
xfaForm.setChanged(true);
XfaForm.setXfa( XfaForm.serializeDoc(xfaForm.getDomDocument()),
stamper.getReader(), stamper.getWriter() );
stamper.close();
pdfr.close();
}
catch (DocumentException f)
{
. . . . . . . . . . .
Up to here it's all ok.
I open the pdf (and the field is populate) I can insert or modify a
value fields and save.
Then I have create another function that read all value from the pdf
//Questa funzione setta gli attributi della geometria prendendo i valori
dal pdf
public static String getAttributi(String nomefile,String campo_ric)
{
//Dichiarazione variabili
PdfReader pdfr;
Set<HashMap> map;
XfaForm xfa;
String campo = "";
String valore = "";
try
{
//get the pdf reader
pdfr = new PdfReader(nomefile);
Node n = pdfr.getAcroFields().getXfa().getDatasetsNode();
Xml2SomDatasets som = new Xml2SomDatasets(n);
map = som.getName2Node().keySet();
xfa = pdfr.getAcroFields().getXfa();
for (Iterator it2 = map.iterator(); it2.hasNext();)
{
campo = it2.next().toString();
if (campo.indexOf(campo_ric) >= 0)
{
valore = xfa.getNodeText(xfa.findDatasetsNode(campo));
}
}
}
catch (IOException e)
{
//TO DO
}
return valore;
}
Node n = pdfr.getAcroFields().getXfa().getDatasetsNode(); is null why?
Why the in PdfStamper getDatasetsNode() is null what I must do?
Please help me
Thanks
Regards
Giovanni Virdis
