Java: Fill Barcode Fields

public static void fillBarcodeFields(Path inputFile, Path outputFile) {
    Form form = new Form();
    try {
        form.bindPdf(inputFile.toString());
        form.fillBarcodeField("product_barcode", "123456789012");
        form.save(outputFile.toString());
    } finally {
        form.close();
    }
}

Java: Fill Fields by Name and Value

Tue, 09 Jun 2026 00:00:00 +0000

The Java FormExamples class fills individual fields directly:

form.fillField("name", "John Doe");
form.fillField("address", "123 Main St, Anytown, USA");
form.fillField("email", "john.doe@example.com");

If your application already has a dynamic set of field names and values, apply the same fillField(...) call inside your own loop:

for (Map.Entry<String, String> entry : values.entrySet()) {
    form.fillField(entry.getKey(), entry.getValue());
}

This is an application-level pattern derived from the same Java API used in FormExamples.fillTextFields(...); the current repository does not include a separate dedicated helper method for map-based filling.
