Hello,
I have problem retreiving the uuid?
here is the scenario:
when i save the file, here is the code:
.................................
Node file = folder.addNode(name, "nt:file");
Node fileContent = file.addNode("jcr:content", "nt:resource");
fileContent.addMixin(JcrConstants.MIX_REFERENCEABLE);
session.save();
uuid = fileContent.getUUID();
..this save fine and some metadata save in DB also including the uuid.
Now i want to delete the file:
Node nodeToRemove = session.getRootNode().getNode(path.substring(1));
String uuid = nodeToRemove.getUUID(); ---> error here
if (nodeToRemove != null)
{
nodeToRemove.remove();
session.save();
//
jcrFileStorageDao.delete(jcrFileStorageDao.loadByUUID(uuid));
}
javax.jcr.UnsupportedRepositoryOperationException
at org.apache.jackrabbit.core.NodeImpl.getUUID(NodeImpl.java:3040)
how can i resolve this?
thanks a lot.
cheers.
