Question

I have locked a node using the below code

ocm.lock("/path1", true, true);

Here the 3rd argument is true which states that it is a Open-scoped Locks.

And it is successfully locked.

But now i am writing a new Java Program to unlock a node.

boolean b1 = ocm.isLocked("/path1");
System.out.println(b1);                      // RETURNS TRUE.
Node n = session.getNode("/path1");
Lock l = n.getLock();
ocm.unlock("/path1", l.getLockToken());

But i am getting a exception here. And it is not unlocking the node.

ERROR [main] ObjectContentManagerImpl.java:957 Cannot unlock path: /path1 Jcr user: admin has no lock token to do this. Lock was placed with user: admin
Exception in thread "main" org.apache.jackrabbit.ocm.exception.IllegalUnlockException
    at org.apache.jackrabbit.ocm.manager.impl.ObjectContentManagerImpl.unlock(ObjectContentManagerImpl.java:958)
    at ocm.UnlockNode.main(UnlockNode.java:36)

How i can unlock the node?

My UnlockNode.java code.

Repository repository = new URLRemoteRepository("http://localhost:8083/rmi");
Session session = repository.login(new SimpleCredentials("admin","admin".toCharArray()));
Mapper mapper = new AnnotationMapperImpl(classes);
ObjectContentManager ocm = new ObjectContentManagerImpl(session, mapper);

LockManager lm = session.getWorkspace().getLockManager();
lm.addLockToken("a096a79c-5edf-4a17-baa4-aba01f8013d8-J");
boolean b1 = ocm.isLocked("/path1");
System.out.println(b1);
try {
    ocm.unlock("/path1","a096a79c-5edf-4a17-baa4-aba01f8013d8-J");
}catch (Exception e) {
    System.out.println(e);
}

Thanks.

Sounds like you’re trying to get the lock from another session…

java.lang.String getLockToken()

May return the lock token for this
lock. If this lock is open-scoped and the current session either holds
the lock token for this lock, or the repository chooses to expose the
lock token to the current session, then this method will return that
lock token. Otherwise this method will return null.

Either get the lock token, after locking, and store it for later or write your own LockManager with a checkUnlock() method that does what you want it to.
