Duplicatable and Disposable JPA Repository for Unit Testing

Hi Folks, I seek an in-memory JPA implementation which can be easily instantiated, populated, and then duplicated for use in separate tests.  Tests might be JUnit or Fitnesse based.  There is no reason for file-system storage (preferably there would be none).  The ability to "duplicate" the populated repository is pretty important, as this allows individual tests to execute quickly (very little spin-up time and no need to pre-populate the db) and to execute without side-effects from other tests (db instance is not shared between tests). #1 2015-06-30 10:02 Hi Folks, I seek an in-memory JPA implementation which can be easily instantiated, populated, and then du ...

evictAll() behavior

I'm writing a multi-user drawing tool, using objectdb as the central store.  When a user press F5, I want to pick up all the changes from the database.  So, I call evictAll() in the following ways: pmf.getDataStoreCache().evictAll();  // the factory pm.evictAll();                                 // the persistence manager A couple of questions about this: 1. the first evictAll() seems to be clearing the L2 cache -- is this correct 2. the evicts only work when they are done inside a transaction -- is this specified in the JDO spec? #1 2010-12-08 23:57 I'm writing a multi-user drawing tool, using objectdb as the central store.  When a user press F5, I want to ...

Good day, We have few troubles with GlassFish on @remote. When we wants to get entity from remote interface, but in the result we have null in all entity fields.
