Hi, when using PDFBox 2 for converting a PDF to PDF/A I get this error:
(same error when creating a new one)
--------------------------------------------------------------
Exception in thread "Root Thread" java.util.ServiceConfigurationError:
java.nio.charset.spi.CharsetProvider: Provider
org.apache.pdfbox.encoding.PDFBoxCharsetProvider not found
That class is 1.8.x specific and no longer available in 2.0.x, so that I assume
that your classpath contains several versions of PDFBox.

at PDFTools.createPDFA(PDFTOOLS:199)
--------------------------------------------------------------
Outgoing from this piece of Code (running in an Stored Procedure in an
Oracle Database):
public static byte[] createPDFA(byte[] pdf) throws Exception {
ByteArrayOutputStream out = new ByteArrayOutputStream();
ByteArrayInputStream in = new ByteArrayInputStream(pdf);
try (PDDocument doc = PDDocument.load(in)) {
// add XMP metadata
XMPMetadata xmp = XMPMetadata.createXMPMetadata();
try {
DublinCoreSchema dc = xmp.createAndAddDublinCoreSchema();
dc.setTitle("insert some title"); // xxx
PDFAIdentificationSchema pdfaid =
xmp.createAndAddPFAIdentificationSchema();
pdfaid.setPart(3);
pdfaid.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 badFieldexception) {
// can't happen here, as the provided value is valid
throw new IllegalArgumentException(badFieldexception);
}
// sRGB output intent
InputStream colorProfile =
PDFTools.class.getResourceAsStream("/org/apache/pdfbox/resources/pdfa/sRGB.i
cc");
PDOutputIntent intent = new PDOutputIntent(doc, colorProfile);
intent.setInfo("sRGB IEC61966-2.1");
intent.setOutputCondition("sRGB IEC61966-2.1");
intent.setOutputConditionIdentifier("sRGB IEC61966-2.1");
intent.setRegistryName("http://www.color.org";);
doc.getDocumentCatalog().addOutputIntent(intent);
doc.save(out);
}
byte[] bytes = out.toByteArray();
return bytes;
}
I am not sure why the serializer uses PDFBoxCharsetProvider that is not
contained in PDFBox 2.
Can anyone help?
Thanks!
Roland
