Subject: [iText-questions] AcroFields ReadOnly, but I but it Obligatory


Hi Bruno and All!

I am new in iText and I am making one "software" for signing PDFs.

This software have any acrofields tagged "Obligatory", and I make the pdf
template with Acrobat Professional (Designer Module) 7.0.

But I run the software I get this:

com.lowagie.text.DocumentException: This AcroFields instance is read-only.
    at com.lowagie.text.pdf.AcroFields.setField(AcroFields.java:965)
    at com.lowagie.text.pdf.AcroFields.setField(AcroFields.java:948)
    at
org.cejug.certificates.local.LocalCertificateBuilder.createEventCertificateEvent
(LocalCertificateBuilder.java:67)
    at org.cejug.certificates.Main.main(Main.java:36)

The iText Version is 2.0.2.

Attached in this mail I send the PDF, and below I put the Code:

PdfReader l_pdf = new PdfReader("CertificadoOriginal.pdf");
AcroFields l_acrofields = l_pdf.getAcroFields();

l_acrofields.setField("evento", "teste");
l_acrofields.setField("participante", "Carlos Delfino");

Thanks for Attention.
