That image was swallowed by the mailing list engine. I point you to my
comment in your SO question
https://stackoverflow.com/questions/70888090/set-pda-a-to-existing-pdf-using-pdfbox
"Converting an existing PDF to PDF/A can be very difficult, it's more
than just setting the metadata."
If you want to convert random files then you should use commercial
tools. PDFBox can only help for simple PDFs, e.g. PDFs from scans.

Thanks Tilman
I was able to run the example now

Because you're not using the 2.0 CreatePDFA.java example. That one
goes
like this:
// add XMP metadata
XMPMetadata xmp = XMPMetadata.createXMPMetadata();
try
{
DublinCoreSchema dc =
xmp.createAndAddDublinCoreSchema();
dc.setTitle(file);
PDFAIdentificationSchema id =
xmp.createAndAddPFAIdentificationSchema();
id.setPart(1);
id.setConformance("B");
XmpSerializer serializer = new XmpSerializer();
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
serializer.serialize(xmp, baos, true);
PDMetadata metadata = new PDMetadata(doc);
metadata.importXMPMetadata(baos.toByteArray());
doc.getDocumentCatalog().setMetadata(metadata);
}
catch(BadFieldValueException e)
{
// won't happen here, as the provided value is valid
throw new IllegalArgumentException(e);
}
