> I will explain what I want to do.
> 1. I have a PDF Document with Fields and let us call this 'Source_Original.PDF'. The field names in this PDF document have to be renamed and stored as 'Source_Target.PDF'. I then have to set/change the values of form-fields in 'Source_Target.PDF'.
> The issue I am facing is given below:
> 1. I renamed the form fields in 'Source_Original.PDF" using the code given in my earlier mail (below) and saved it as 'Source_Target.PDF'.
> 2. I checked the form fields in 'Source_Target.PDF" and form-fields were renamed correctly.
> 3. However when I tried to set/change values of form-fields in 'Source_Target.PDF' using PDFBox code, I was not able to do so.
> I used iText to set/change values of form-fields in 'Source_Target.PDF' and was successful. But we want to use only PDFBox.
> To summarize - We are not able to set/change values of form fields of a PDF Document whose form-fields have been renamed. There is no issue if the form-fields are renamed manually using Adobe Acrobat 9. The issue is only
> when the form-fields are renamed using PDFBox option - setPartialName(newFieldName);
> > Only to be sure, changing values in 'Source_Original.PDF'  works with the same code you use to 
> > manipulate 'Source_Target.PDF'??
> Yes
> I have attached the 2 files - "Source_Original.PDF' and 'Source_Target.PDF',
> ----- Code
> 				try
> 				{
> 					PDDocument pdfDocument = PDDocument.load(pdfSource);
> 					try
> 					{
> 						if (pdfDocument.isEncrypted())
> 						{
> 							pdfDocument.decrypt("");
> 						}
> 						PDDocumentCatalog docCatalog = pdfDocument.getDocumentCatalog();
> 						PDAcroForm acroForm = docCatalog.getAcroForm();
> 						if (acroForm != null)
> 						{
> 							List pdfFields = acroForm.getFields();
> 							if (pdfFields != null)
> 							{
> 								PDField pdfField;
> 								for (int i = 0; i < pdfFields.size(); i++)
> 								{
> 									pdfField = (PDField) pdfFields.get(i);
> 									String fieldName = pdfField.getPartialName();
> 									if( pdfFieldNames.containsKey(fieldName) ){
> 										String newFieldName = (String) pdfFieldNames.get(fieldName);
> 										pdfField.setPartialName(newFieldName);
> 									}
> 								}
> 								pdfDocument.save(pdfOutput);
> 							} else {
> 								return "No Acro Form Fields found in PDF Document " + pdfSource + "!";
> 							}
> 						} else {
> 							return "PDF document " + pdfSource + " not able to access!";
> 						}
> 					} catch (Exception e) {
> 						return "PDF Document " + pdfSource + " is encrypted! Cannot process.";
