Failing to read entities under load in multithreaded tests

Hi, We are experiencing an issue in our application that only occurs under load - we sometimes fail to read entities from the database. ... InheritanceType . TABLE_PER_CLASS ) @ TableGenerator ( name = "TestIdTableGen" , initialValue = ...

Possible issue with timestamps

Hi, If I query doing something like: select c from CDI c where c.creationDate > {ts '2012-03-29 11:00:00} and c.creationDate < {ts '2012-03-29 12:00:00'} the test fails. Its ONLY for 12:00:00. When I started digging I found that if I queried 00:00:00 to 00:25:00 and then did 12:00:00 to 12:25:00 I got IDENTICAL results. For some reason 12:00:00 is being treated the same as 00:00:00. All other hours seem to be fine. ... } @ Entity @ TableGenerator ( name = "IdTableGen" , initialValue = 1 ...

Criteria query error: Unexpected query token

Using JPA2, I can save entities now in JBoss, and also fetch them uniquely by id. However, if I try to fetch it by getting back all instances (e.g. findAll, I get the following error: ...

@SequenceGenerator and single id in whole database

Hi, I have a question about @SequenceGenerator. I have separate @SequenceGenerator in each of my model enitities, but it looks like id's are generated using only one, shared generator. Is there any other way to use separate generators for each entity, so that each entity uses its own sequence just like in RDBM?... By using multiple @SequenceGenerator and/or @TableGenerator definitions (with different name values), and attaching ...
