****Part 1:
I receive an exception while trying to import the ³/jcr:system² node into
³/³: javax.jcr.ItemExistsException: Node with the same UUID exists:node
/jcr:system
When I run through debug mode the node IDs are not equal causing
Jackrabbit to throw the exception:
existing.getId() = "deadbeef-cafe-babe-cafe-babecafebabe²
id = null
My simple import code:
ByteArrayOutputStream out = new ByteArrayOutputStream();
session.exportSystemView("/jcr:system", out, false,
false);
System.out.println("WAIT: "+ new
String(out.toByteArray()));
//Insert a breakpoint here to modify data before replacing the current
data, simple test
InputStream in = new
ByteArrayInputStream(out.toByteArray());
session.importXML("/", in,
ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING);
session.save();
Jackrabbit code in SessionImporter (line 377 for Jackrabbit 2.6.5 (my
current version) (also exists for the same line in 2.10.0¹s version)):
if (!(existing.getId().equals(id)
&& (uuidBehavior ==
ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING
|| uuidBehavior ==
ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING))) {
throw new ItemExistsException(
"Node with the same UUID exists:" +
existing);
}
I would venture to say the Node with the same UUID does not exist
(assuming ID is equivalent to the UUID being reference by the errorŠ).
The error description should be a bit different, or add more information.
The XML I¹m trying got import is about 5,624 lines long, but I doubt
people want to receive that in their inbox.
****Part 2:
When I import the ³/jcr:system² node into a subfolder (like /z,
nt:unstructured) it only brings in the 2nd level of children from
³/jcr:system² (jar:versionStorage, jar:activities, jcr:nodeTypes). It
doesn¹t bring in any versions! The export has all the data but the import
is deleting the important information. Some configuration for my current
system:
Repository.OPTION_XML_IMPORT_SUPPORTED is true
In my repository XML I have the following that helps with importing the
ACLs:
<Import>
<ProtectedNodeImporter
class="org.apache.jackrabbit.core.xml.AccessControlImporter"/>
</Import>
By default shouldn¹t Jackrabbit just import everything? Start with being
able to import everything and narrow scope through configuration. At
least then devs would be able to use expected features easily. I would
prefer to just export ³/³ and import into ³/³, but:
javax.jcr.nodetype.ConstraintViolationException: Unexpected node type
{internal}ACL. Should be rep:AccessControl or rep:PrincipalAccessControl.
Sincerely,
-Annoyed I¹m still using this.
