ODB tries to create log files inside its own jar on Win7

I sent a demo of an app I've been developing on Linux to some Windows 7 users, and they were unable to run it.  The stack traces they sent me indicated that ODB was trying to create its log files inside objectdb.jar, which was inside the executable jar packaged by Eclipse.  Here's the end of the stack trace: #1 2012-04-18 02:47 I sent a demo of an app I've been developing on Linux to some Windows 7 users, and they were unable to run it ...

IDs of Entities suddenly became UUIDs?

Hi, We're having our system with ObjectDB 2.4.5 in production since this year April and it works just fine. However, now we've discovered that suddenly partial Objects in some DBs in production do have a UUID String as their id instead of Long which is of course causing a lot of troubles. Note that this even occurrs on the same "Table" -- some saved Entitities of same type do still have a Long ID, others a String UUID. Our Base-Entity everything inherits from is declared as usual with Long: #1 2013-10-17 11:42 Hi, We're having our system with ObjectDB 2.4.5 in production since this year April and it works just ...

persistence.xml classes not respected by ObjectDB

Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ their embeddable classes). P2 is created properly, but P1 gets all entity classes (from P2 also). How can this be avoided, so that both P1 and P2 get just the classes that were specified to each? There is no place in code where P1 tries to access classes from P2, so it makes no sense. #1 2013-08-20 07:48 Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ the ...
