Upgrade to 2.4.1_03

Right, that fix to 2.4.1_02 got us past the previous issue. Now I'm not sure whether this next issue is our annotations, or another issue with objectdb. I have added some more classes to the unit test. They are used by AbstractContactDetail. On line 372 of the attached test, AbstractContactDetail extends AttributeHolder. If I remove the extends, the test passes. If I add it, it fails. I'm not even adding anything to AttributeHolder as part of this test. The exception I get with the extends is: #1 2012-07-05 04:51 Right, that fix to 2.4.1_02 got us past the previous issue. Now I'm not sure whether this next issue is our a ...

Password Protect Database File

Is there a way to encrypt the odb file so that if hackers somehow steal it they cannot access the data without some kind of password? I would imagine accessing the database from java could just have another connection parameter while accessing from explorer.jar/exe would need to prompt the user for a password for encrypted odb files. ... In which case objectdb will only be useful/secure for entities that have the capacity to implement their own hosting solution? ...
