[OJB-developers] new release 0.7.277

[Thomas M. <tho...@ho...>]

Hi all,

I just published a new release.
Prominent new feature is support for Logging. I did not implement a
LOG4J based logger but provided an interface that will allow to use
LOG4J or JDK1.4 logging or whatsoever.
For the time being I'm providing a minimalistic implementation
"PoorMansLoggerImpl".
Logging is now configurable through the OJB.properties file.

Getting Proxies properly working with ODMG tranactions was quite tricky.
I had to introduce a new callback concept in The Proxy
IndirectionHandlers.

The most important change:
I had two complete code walkthroughs to refactor the Exception handling.
I hope that it will now throw all exceptions to user applications.
If you discover any mistakes or find that still some things don't work:
please drop me a line.

from the release notes:

new features:
- Provide full column name information  in ClassDescriptor
- Sortable 1:n associations
- Integrate LOG4J (must use the preprocessor to avoid logging in
production code)
- Integrate getUnique implementation from Jim
- Improve OQLQuery transaction handling if transaction was not opened 
- SELECT DISTINCT support from Jakob

bug fixes:
- ODMG commit must throw TransactionAbortedException if an abort occurs.
- Delete null references: bug
- Transactionimpl.register(...) does not work properly for Proxies
- Correct ODMG checkpoint semantics
- Don't hide exceptions during queries, updates and inserts but reach
them to client app !
- M:N bug: use full qualified column names
- Correct documentation regarding fk_descriptor_ids

refactorings:
- Cache synchronization
- JUNIT tests for Path expresseions
- Remove System.out.println() from JUNIT tests
- Improvements of RsIterator
- Introduce a GUID class

best regards,
and all the best to all of you for the new year!

Thomas
