Node Id of copied Node in Jackrabbit not found on delete
I copied a node to Jackrabbit using session.getWorkspace().copy(sourceNode.getPath(), destinationNode.getPath())
Changes to this operation are saved instantly as far as I know. But when I tried to get the copied node to delete it with session.getNodeByIdentifier("nodeId of copied node")
, it gives an ItemNotFoundException. The reason for this error is that the copied node loses the property mix:referenceable
during copying, which causes getNodeByIdentifier to fail.
The question is how to set the property mix:referenceable
to copy a node as I cannot get the node from the session after the copy operation. Can anyone help me with this?
UPDATE:
CODE:
Node srcNode = session.getNodeByIdentifier("SOURCE_NODE_ID");
if(srcNode == null) {
System.out.println("File not found");
}
Node rootNode = session.getRootNode();
Node appNode = rootNode.getNode("JACKRABBIT");
Node destNode = appNode.addNode("Copy_Test_"+System.currentTimeMillis(),"nt:file");
session.getWorkspace().copy(srcNode.getPath(),destNode.getPath());
destNode.addMixin(MIX_VERSIONABLE);
destNode.addMixin(MIX_LOCKABLE);
destNode.addMixin(MIX_REFERENCEABLE);
destNode.addNode(DMSConstants.RESOURCE_NODE,"nt:unstructured");
session.refresh(true);
session.save();

Please note that I am using JCR 2.0. Also if I change the code to session.refresh(false)
, the code works fine, but I was unable to find the node id from the session to remove the same as my original problem.

Why are you creating a node at the destination and then copying it to the same location? I believe the deprecated exception is because the call has copy
updated the underlying node, making your link destNode
obsolete / obsolete.
Just remove addNode
, then do something like ...
String destPath = "Copy_Test_" + System.currentTimeMillis()";
session.getWorkspace().copy(srcNode.getPath(), destPath);
Node destNode = session.getPath(destPath);

As @TedTrippin pointed out, the problem was creating the destination node before the copy, which was not required. As part of the copy, a node is created. So my final working code looks like this:
Node srcNode = session.getNodeByIdentifier("SOURCE_NODE_ID");
if(srcNode == null) {
System.out.println("File not found");
}
Node rootNode = session.getRootNode();
Node appNode = rootNode.getNode("JACKRABBIT");
String destNodeName = "Copy_Test";
session.getWorkspace().copy(srcNode.getPath(),appNode.getPath() + "/" + destNodeName);
Node destNode = appNode.getNode(destNodeName);
destNode.addMixin(MIX_VERSIONABLE);
destNode.addMixin(MIX_LOCKABLE);
destNode.addMixin(MIX_REFERENCEABLE);
session.refresh(true);
session.save();
