Using Java and IText, how to extract AcroForm field names from PDF?

Question

I am looking for a simple example API that reads a PDF file / template as input and iterates over fields defined in a PDF form (I think this is called AcroForm)

Answer 1

Ok i found a solution

public static void scanFields(String path) throws IOException { PdfReader pdfReader = new PdfReader(path); AcroFields acroFields = pdfReader.getAcroFields(); HashMap<String,AcroFields.Item> fields = acroFields.getFields(); Set<Entry<String, Item>> entrySet = fields.entrySet(); for (Entry<String, Item> entry : entrySet) { String key = entry.getKey(); } }
