[ann] new release 0.9.9
Hi all,
I've just assembled the latest release of our favourite software.
Thanks to all who helped to get this done!
From the release notes:
========================================================================
ObJectRelationalBridge -- Bridging Java Objects and Relational Databases
========================================================================
ObJectRelationalBridge (OJB) is an Object/Relational mapping tool that
provides transparent transactional persistence for Java Objects against
relational databases.
OJB supports ODMG and JDO.
---------------------------------------------------------------------
Release 0.9.9
---------------------------------------------------------------------
NEW FEATURES:
- With this release we are feature complete for the 1.0 release!
For 1.0 you should not expect more features to be added.
CHANGES:
- Metadata handling was improved. The persistent object
metadata is decoupled from the connection metadata.
- Multiple database support was simplified. Now you only
need one repository file and it is allowed to define several
jdbc-connection-descriptors in the repository file.
- In the PBKey we now use an alias name (and user/password)
to match the connection (jdbc-connection-descriptor), instead
using the path to the repository file.
- Remove the "max. connections in pool" property from OJB.properties,
this could be done separate for each database in the repository
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
jdbc-connection-descriptor.
- Refactored sequence package, better support for database
based id gerneration.
- The connection factory implementations using connection
pooling (ConnectionFactoryDBCPImpl, ConnectionFactoryPooledImpl)
now support a 'validationQuery' to check if the returned pooled
connection is valid.
- Make JdbcAccess, ConnectionManager, StatementManager pluggable
via setting in OJB.properties
- PersistenceBroker api changes of methods used in kernel
getExtentClass ---> getTopLevelClass
getConnectionManager --> serviceConnectionManager
getStatementManager --> serviceStatementManager
getUniqueXXX methods removed ---> use serviceSequenceManager instead
add new method removeListener
- Improve the OJB performance test suite. Add a simple test
framework to allow comparison of OJB with other O/R mapping tools.
BUG FIXES:
- tons of bug fixes
More information is available at http://db.apache.org/ojb
I hope you enjoy the new release,
cheers,
Thomas

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