Hi,
I am working on an application which should hold multiple versions of images.
While retrieving those versions I am getting all the properties but the
image,what I am getting is the latest image what is stored.
I have added img1.png ,
Then I have updated it to img2.png, img3.png, img4.png.
All are of different resolutions and sizes.
When trying to retrieve the versions, I could get all four versions of images,
but all contain img4.png only.
I tried printing the no of bytes of each version's inputStream, I am getting
the actual sizes.
VersionHistory versionHistory = photocontent.getVersionHistory();
VersionIterator versionIter = versionHistory.getAllVersions();
versionIter.skip(1);
InputStream imageDataStream = null;
String imageMimeType = null;
while (versionIter.hasNext()) {
Version version = versionIter.nextVersion();
log.info("version "+version.getUUID());
log.info("version created time "+version.getCreated().getTime());
NodeIterator nodeIter = version.getNodes();
while(nodeIter.hasNext()) {
Node versionedNode = nodeIter.nextNode();
//Node versionedNode =
version.getNode(JcrConstants.JCR_FROZENNODE);
imageDataStream =
versionedNode.getProperty(JcrConstants.JCR_DATA).getStream();
imageMimeType =
versionedNode.getProperty(JcrConstants.JCR_MIMETYPE).getString();
if (imageDataStream != null && imageMimeType != null) {
log.info("no of bytes "+imageDataStream.available());
DataSource source = new
ByteArrayDataSource(imageDataStream, imageMimeType);
candidateContent.setContent(new DataHandler(source));
Can you please help me in resolving this issue
Regards,
