Hi,
I am experiencing problems with the import functionality of Jackrabbit. It
appears that the import mechanism fails when there are references to nodes that
are marked as 'mandatory autocreated' in the CND file. I have written a small
Java application (with a simple CND-file) that reproduces this problem. The
ReferentialIntegrityException that is thrown states that the object being
referenced does not exist, but it does exist in the XML being imported (The
'missing' object is the mandatory autocreated object). Is this a bug, or is
this particular configuration unsupported in Jackrabbit?
Environment:
Jackrabbit Core 1.4.6.
jdk1.6.0_07.
Fedora 9 Linux (also reproduced on Windows).
The repository configuration used by my test application uses
org.apache.jackrabbit.core.fs.mem.MemoryFileSystem and
org.apache.jackrabbit.core.persistence.mem.InMemPersistenceManager.
Stacktrace, cnd-file, and Java code are listed at the bottom of this e-mail.
Regards,
Audun

My CND file is as follows:
----------------------------------------
[test:Container]> nt:base
+ * (nt:base) multiple
[test:Child]> nt:base, mix:referenceable
[test:Parent]> nt:base
+ test:Test (test:Child) = test:Child mandatory autocreated
[test:Linked]> nt:base
- test:linked (reference) mandatory
------------------------------------------------------------------------
The Java-code that reproduced the problem is as follows:
------------------------------------------------------------------------
try {
Node container =
session.getRootNode().addNode("container", "test:Container");
Node parentNode = container.addNode("Test",
"test:Parent");
Node childNode = parentNode.getNode("test:Test");
Node linkedNode = container.addNode("Link",
"test:Linked");
linkedNode.setProperty("test:linked", childNode);
session.save();
ByteArrayOutputStream bout = new
ByteArrayOutputStream();
session.exportSystemView(session.getRootNode().getNode("container").getPath(),
bout, false, false);
bout.flush();
bout.close();
container.remove();
session.save();
session.importXML(session.getRootNode().getPath(), new
ByteArrayInputStream(bout.toByteArray()),
ImportUUIDBehavior.IMPORT_UUID_COLLISION_THROW);
// This save() call fails with a
ReferentialIntegrityException
session.save();
} catch (Exception e) {
throw new IllegalStateException("oops", e);
}
