JpegXMPWriter throws NullPointerException
-----------------------------------------
Key: SANSELAN-19
URL: https://issues.apache.org/jira/browse/SANSELAN-19
Project: Sanselan
Issue Type: Bug
Environment: Windows XP, JDK 1.5
Reporter: Kelly Boettcher
I am try to use the JpegXMPWriter to write xmp values from a Jpeg file. Using
JpegImageParser, I can retrieve existing xmp values out the file fine. However,
attempting to write back into the file produces an exception.
byte[] b = null;
String existingXMP = null;
String newXMP = null;
XMPMeta meta = null;
Document licenseDoc = null;
JpegImageParser parser = null;
JpegXmpRewriter xmpWriter = null;
ByteArrayOutputStream baos = null;
b = new byte[is.available()]; // is is a jpeg input stream passed into the
function.
is.read(b);
is.close();
parser = new JpegImageParser();
ByteSourceArray bs = new ByteSourceArray(b);
existingXMP = parser.getXmpXml(bs, null); // works fine, passes back valid xmp
from the file
/* I did have other functionality here to manipulate the xmp which
works fine, but I also ran the test without changing the xmp,
with the same resulting exception. */
baos = new ByteArrayOutputStream();
xmpWriter.updateXmpXml(bs, baos, existingXMP); // NullPointerException occurs
here.
b = baos.toByteArray();
is = new ByteArrayInputStream(b);
return is;
Exception produced:
java.lang.NullPointerException
