Pojo (Tree Cache) locking question

[shalnagr]

Hello

I am trying to use the org.jboss.cache.lock.* package
in order to obtain (replicated) cache wide Object Locking.

Using the IdentityLock class I have managed to lock (write locks) objects (annotated pojos) on a single node.
For some reason the lock does not seem to prevent other nodes in the cluster
, from obtaining locks to the same object.
Is it because I am using the DummyTransactionManager preconfigured in the release's example XMLs
I am using 1.4GA version.
The
? tx.start
pojo1.setField1();
pojo2.setField2() ;
tx.commit()
?
Way of doing things is not going to workout for me.
I Really need cluster wide directlocks.

Many Thanks

Shal.

JBoss Cache is not using the distributed locking semantics. So I don't think there is an easy to botain distributed locking.

1) what about a hard way to obtain botain distributed locking? can ... say Jboss Transactions
help me out ?

2) what about TreeCache Treansactions ?

tx.start
pojo1.setField1();
pojo2.setField2() ;
tx.commit()

is this transaction distributed?

Re: 2. No, it is not in your sense. Locking is again done on local node first before commit.
