Acquire lock

[superuser33]

Hi, just started evaluating JBossCache for our clustering needs, and i was not able to find a simple clusterwide readLock / writeLock. Is this available/supported through JBossCache or JGroups at all?

Ideally it would be something as simple as
------------------------------------------------

ClusterLock lock = tree.acquireReadLock("/key/a",30000L); //30 second timeout
try {
 //do stuff
} finally {
tree.releaseReadLock("/key/a");
}

Nope, we don't do cluster-wide locking. Instead we use 2PC transactions to maintain integrity across a cluster.
