-------------------------------

                 Key: JBCLUSTER-223
                 URL: https://jira.jboss.org/jira/browse/JBCLUSTER-223
             Project: JBoss Clustering
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: HA-Server-API
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
             Fix For: HA-Server-API 1.2.0.GA


Useful for clustered DeploymentRepository and for ensuring only one node accesses a web session or SFSB at a time.

This will be different from the JGroups DistributedLockManager is two main respects:

1) Built on HAPartition instead of RpcDispatcher.  This is actually a negative, but I want this to be able to use the same channel the AS's HAPartition uses.  Perhaps I'll develop a separate API and an adapter implementation that directly uses RpcDispatcher to provide flexibility going forward.

2) Acquiring a lock requires a callout to a pluggable LocalLockHandler. This is to support more sophisticated interaction with the service using the lock manager.

I probably won't use the two-phase approach the JGroups DistributedLockManager adopts either.
