Hey Max,

What do you mean by "threadsafe handling of the objects without relying on
locking"? Could you give an example. 

Raghu.

Any light in the tunnel for threadsafe handling of the objects without
relying on locking them via ODMG ?

> NEW FEATURES:

> CHANGES:

> file using the connection-pool element.

> - Move sequence manager configuration from OJB.properties into the
> repository file (see sequence-manager element in repository.dtd).
> Now it's possible to define a separate sequence manager for each

> - The connection factory implementations using connection
> pooling (ConnectionFactoryDBCPImpl, ConnectionFactoryPooledImpl)
> now support a 'validationQuery' to check if the returned pooled
> connection is valid.

> - Improve the OJB performance test suite. Add a simple test
