[~msahyoun] Yes perfect that did the trick...
By the way how did you highlight the {{UnsupportedOperationException}} in your
post?

> Key: PDFBOX-3524
> URL: https://issues.apache.org/jira/browse/PDFBOX-3524
> Project: PDFBox
> Issue Type: Sub-task
> Components: Signing
> Affects Versions: 2.0.3
> Reporter: Tilman Hausherr
> Assignee: Maruan Sahyoun
> Fix For: 2.0.4, 2.1.0
>
>
> In the CreateEmptySignatureForm example, adding
> {code}
> signatureField.setValue(new PDSignature());
> {code}
> before saving brings this
> {code}
> Exception in thread "main" java.lang.UnsupportedOperationException: not
> implemented
> at
> org.apache.pdfbox.pdmodel.interactive.form.PDSignatureField.constructAppearances(PDSignatureField.java:237)
> at
> org.apache.pdfbox.pdmodel.interactive.form.PDTerminalField.applyChange(PDTerminalField.java:226)
> at
> org.apache.pdfbox.pdmodel.interactive.form.PDSignatureField.setValue(PDSignatureField.java:121)
> at
> org.apache.pdfbox.examples.signature.CreateEmptySignatureForm.main(CreateEmptySignatureForm.java:84)
> {code}
> Although there's nothing to construct, visual signing is a different area of
> PDFBox.
> What does work is this:
> {code}
> signatureField.getCOSObject().setItem(COSName.V, new PDSignature());
> {code}
> I wanted to add this line because this would make it possible to sign this
> specific field with PDFBox, due to the findSignatureField() method in
> PDDocument, which would allow to pre-fill a PDSignature object.
