session export / import
hi all,
I'm developing a way of doing backups of our JCR repository built with
Jackrabbit.
I started by creating a node "/bruno" and used
*session.exportDocumentView("/", outputStream, skipBinary, noRecurse);*
to export all the content to a xml file.
then I use
*session.importXML("/", inputStream,
ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING);*
to import the xml file:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root jcr:primaryType="rep:root" xmlns:fn="
http://www.w3.org/2005/xpath-functions" xmlns:fn_old="
http://www.w3.org/2004/10/xpath-functions" xmlns:xs="

jcr:sameNameSiblings="false"/></ctgt:nosamenamesiblings>
[...]
</jcr:nodeTypes>
</jcr:system>
<bruno jcr:primaryType="ctgt:nosamenamesiblings"
creationDate="1277226878544" deleted="0" lastModifiedDate="1277226878544"
name="/bruno" objectFQN="yunit.contingut.content.dataObjects.Folder"
status="WORK_IN_PROGRESS"/>
</jcr:root>
my problem is that the import creates another node instead of replacing the
existing one.
it creates a node in /jcr:root/bruno and should replace the node /bruno.
from the specification the importer uses the UUID to check if the node
exists in the target repository
but I open the xml file there's no UUID in the attributes of the nodes.
is this correct? if so how can the importer know if a node already exist or
not?
am I doing something wrong?
thanks in advance.
best regards,
bruno coelho

sorry all for disturbing you with this problem...
I looked again at the node type definition and is wrong, that was the
problem.
thanks again.

Re: session export / import
Posted by bruno coelho <br...@gmail.com>.
hi,
I tried what Justin said.
I deleted my repository, it was jsut for tests.
I removed the registred node type and redefine the node type adding the
mixin:
<ctgt = 'http://www.yunit.pt/contingut/ctn/1.0'>
[ctgt:nosamenamesiblings]
orderable *mixin*
- * (UNDEFINED) multiple
- * (UNDEFINED)
+ * (nt:base) = ctgt:nosamenamesiblings VERSION
then I registered the node.
the problem now is that I can't create a node:
javax.jcr.nodetype.ConstraintViolationException: Unable to add a node with a
mixin node type: ctgt:nosamenamesiblings at
org.apache.jackrabbit.core.NodeImpl.addNode(NodeImpl.java:1471) at
org.apache.jackrabbit.core.NodeImpl.addNodeWithUuid(NodeImpl.java:2087) at
org.apache.jackrabbit.core.NodeImpl.addNode(NodeImpl.java:1992) at
I looked at the code:
if (nodeTypeName != null) {
nt = session.getNodeTypeManager().getNodeType(nodeTypeName);
if (nt.isMixin()) {
throw new ConstraintViolationException(
"Unable to add a node with a mixin node type: "
+ session.getJCRName(nodeTypeName));
}
[...]
by that I can only assume that you can not create a node with a custom node
type that is mixin.
is my assumptation correct?
can you please help me.
thanks in advance.
best regards,
bruno coelho

You need to use referenceable nodes. Simply adding the mixin
mix:referenceable to the nodes you want to replace or add the mixin as a
parent node type at the time of node type creation (last I checked JR
doesn't allow for mixins to be added to a node type once the type has
been created) should do the trick. However, I would suggest using system
view especially when dealing with unstructured data (unless I'm missing
something ctgt:nosamenamesibilings is basically nt:unstructured without
support for SNS).
