The ODMG api works fine in one JVM. It also works fine on really distributed ones =)

Another in-jvm database worth considering is Axion ( http://axion.tigris.org/features.html ) -- it is transactional, but development seems to have slowed on it as the last release was almost a year ago =/

The OTM is usable, but I wouldn't use it for critical apps quite yet. FWIW, we maintain ODMG and OTM implementations of our repository side by side and they both work fine in all cases so far -- the ODMG is in production though, not the OTM =/

I would call the OTM released-but-unstable in 1.0 and ODMG stable. ODMG can provide the same object-space transaction isolation you are looking for, I think.


I've read that ODMG is for massive distribute environments, but my application runs in one JDK and my database runs in same jdk (I find that only hsql is LGPL and can work in the same jdk, but it didn't have transaction isolation).
Does anybody try to use LockManager without OTM ?
