[OJB-developers] [ann] new release

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

Hi all,

I just released a new release. There are some new features and a lot of 
bug fixes.

Simon provided a complete rewrite of the OQL parser. All OQL related 
bugs should be fixed and some cool new things like subselects are 
possible now! Thank you Simon!


There had been a request regarding batch operation with OJB. I fixed the 
ObjectModification mechanism and rewrote the PerformanceTest to have a 
separate view on broker.store(obj,true), broker.store(obj,false), 
broker.getObjectByIdentity(...), broker.delete(obj) performance.

Just try build.sh performance to see how long it takes to insert, 
update, select, delete 5000 objects. You can even change the build.xml 
file to increase the number of objects.


 From the release notes:
