Examples of LockService

Manages the distributed lock

@author John Sanda
org.apache.rave.service.LockService
Service used to manage shared Lock objects to be used for item level synchronization.
org.jgroups.blocks.locking.LockService
ing.xml needs to have a locking protocol towards the top LockService lock_service=new LockService(ch); ch.connect("lock-cluster"); Lock lock=lock_service.getLock("mylock"); lock.lock(); try { // do something with the lock acquired } finally { lock.unlock(); } Note that, contrary to the semantics of {@link java.util.concurrent.locks.Lock}, unlock() can be called multiple times; after a lock has been released, future calls to unlock() have no effect. @author Bela Ban @since 2.12
