Martin Hilpert updated PDFBOX-823:
----------------------------------
Summary: NullPointerException in
DateConverter.toISO8601(DateConverter.java:221) (was: DocumentInformation is
not visible (with Acrobat Reader))
Affects Version/s: 1.2.1
(was: 1.3.0)
Description:
I tried to add metadata as shown in AddMetadataFromDocInfo.java. There's also
the line
basicSchema.setModifyDate( info.getModificationDate() );
but I get a NullPointerException at this line:
java.lang.NullPointerException
at
org.apache.jempbox.impl.DateConverter.toISO8601(DateConverter.java:221)
at org.apache.jempbox.xmp.XMPSchema.setDateProperty(XMPSchema.java:249)
at
org.apache.jempbox.xmp.XMPSchemaBasic.setModifyDate(XMPSchemaBasic.java:266)
because the info.getModificationDate() returns null. It would be better to
catch null parameters in the metadata set methods.
Workaround:
if (pddi.getModificationDate() != null) {
basicSchema.setModifyDate(pddi.getModificationDate());
}//else: avoid NPE
was:
I try to set PDF document inforamtion
(http://pdfbox.apache.org/userguide/metadata.html), but the final PDF doesn't
have my information set! E.g.
final PDDocumentInformation pddi = doc.getDocumentInformation();
pddi.setAuthor("MeAndMyself");
I debugged and ensured that after creation of PDF with APache FOP, this is the
last action on the PDF done. But when viewing with Acrobat Reader, only the
information that I set during FOP rendering is shown.
But then I noticed that when I view the PDF file with FoxIt Reader (4.0), File
> Properties show all the properties I set like Title, Author, Producer.
Viewing this exact same PDF file with Acrobat Reader (9.3.4), this properties
are not shown (and some other properties are shown I set during the first FOP
PDF Rendering to produce the PDF).
I wonder if there are multiple ways to store such information in a PDF? Why is
showing FoxItReader the properties I set afterwards with PDFBox, but Adobe
Reader ignores those Properties and show the properties set on the first PDF
generation?
Component/s: JempBox

Found XMP Metadata example.
