Hi,
I am planning to use open-scoped lock. For which , I need to persist
the locktoken along with the node so that it can be used by another
session for unlocking.Tested with Jackrabbit RMI client and it works fine.
But I am using jcr-mapping layer to achieve the above in my project.Here
I want that as soon as a node is checked out, it gets locked by the
session and the lock is stored in "lockToken" property of node
"Document". For that I need to update the Document node after locking .
*public void checkout(String path)throws CMSException {
pm = getPersistenceManager();
try{
pm.checkout(path);*
* String lockToken = pm.lock(path,true,false);
** Document doc = this.getDocument(path);**
doc.setLockToken(lockToken); //for persisting lockToken
doc.update();
}catch(LockedException le){
System.out.println(le.getLockedNodePath() + "is locked by" +
le.getLockOwner());
}catch(Exception e){
throw new CMSException(e.getMessage(),e.getCause());
}
}*
Here doc.update() fails with Locked Exception. The problem here is
PersistenceManagerImpl has a method checkIfNodeLocked(path) which
returns LockException if node is locked. This method is checked before
every update/insert. So, I am not able to update a locked node. I need
to persist the locktoken in the node . What is the reason of checking
for a lock before saving ? Ideally , it should throw error only if node
is locked and session does not hold the lockToken .
If the session who has locked the node tries to save the node without
unlocking, it should be allowed .
p.s.
I am able to achieve the above by simple Jackrabbit RMI client.
<code>
ClientRepositoryFactory factory = new
ClientRepositoryFactory();
Repository repository =
factory.getRepository("rmi://localhost:1101/jackrabbit");
Session session = repository.login(new
SimpleCredentials("superuser",
"superuser".toCharArray()),"Portal");
String user = session.getUserID();
String name =
repository.getDescriptor(Repository.REP_NAME_DESC);
System.out.println(
"Logged in as " + user + " to a " + name + "
repository.");
/* Testing the locks functionality */
Node n =
session.getRootNode().getNode("cms/childfolder1/check.txt");
* Lock lck = n.lock(true, false); // deeplock,open-scoped
n.setProperty("ps:locktoken",lck.getLockToken());
n.setProperty("ps:language", "sanskrit");
*
System.out.println("Lock#isLive=" + lck.isLive());
System.out.println("Node#isLocked=" +
session.getRootNode().getNode("cms/childfolder1/check.txt").isLocked());
session.save();
session.logout();
<code>
Help appreciated.
Thanks,
