> Here is a code snippet
> {code:java}
> PDDocument pdfDocument = PDDocument.load(new File("a.pdf"));
> pdfDocument.setAllSecurityToBeRemoved(true);
> PDDocumentCatalog docCatalog = pdfDocument.getDocumentCatalog();
> PDAcroForm acroForm = docCatalog.getAcroForm();
> if (acroForm != null) {
>   PDField field = (PDField) acroForm.getField("nas");
