Norbert, There is no such standalone TableGenerator in JPA but some solution to this has been recently posted here: http://n2.nabble.com/Access-Oracle-Sequence-using-OpenJPA-tp2227943p2227943.html Hope this helps. Greetings, Milosz Hi, for some reason I need a sequence generator, used

Hi, Setting a batchLimit to -1 indicates there is no limit. Normally, this would not be good since you could run into out of resources (memory, connections, locks, etc) type situation. So, I wouldn't suggest running with batchLimit set to -1 for any database. Setting it to 0 turns it off. By

Personally, I would recommend the use of one of OpenJPA's id generators. I've worked with our test organizations that wanted to develop their own id generators and they continue to run into locking and synchronization problems. If you can use the OpenJPA generators, then your application doesn't

Adam's observations seem in synch with mine. Although I don't have personal experience with storing localized data, I have exchanged e-mails with a few people who have attempted it with the OpenJPA Entity Listeners. No reference accounts per se, but it does seem doable. Kevin On Mon, Feb 2,

Hi, I haven't been able to set a 'delete orphan' cascade yet. OpenJPA supports delete-orphan semantics. Annotate the relationship with @Dependent annotation. For further details, please refer the doc [1] [1] http://openjpa.apache.org/builds/latest/docs/manual/manual.html#dependent -- View

Gianny - I see in a later post that you figured out that your persistence.xml file wasn't in your classpath, but I'm wondering how this problem was manifesting itself? ie: What were the error messages that you were seeing? Also, what JDK are you running on. Thanks, Rick Gianny Damour wrote:

'Standalone' Sequence Generator

2009-02-02 Thread Norbert Rieger
Hi, for some reason I need a sequence generator, used to create unique keys explicitly. Is there any kind of standalone TableGenerator available in JPA ? What I want to do is something like that: TableGenerator genId = new TableGenerator (em, XX) ; Long next = genId.getNext () ;

Hi Rick, actually I use maven but I also run them all or partially in Eclipse, especially when debugging, and especially when there is some fiendish hidden static somewhere that carries over state from one test to the next, despite all the precautionary set-up and tear-down code. Rick

Issue with FetchAttribute recursionDepth

2009-02-02 Thread Brian Dellert
Hi. I am attempting to leverage the recursionDepth FetchAttribute on one of my JPA entity classes, but OpenJPA does not seem to be honoring the value. Even if I specify a recursionDepth of 50, a load of the object graph is only returning a recursionDepth of 1. I am using a FetchGroup on the

Hi Brain, You have defined a FetchGroup named subEntities with arecursion depth of 50 alright. But defining a fetch group does *not* activate it. The fetch group which is active by default is called default and includes fields of basic types only. One way to activate subEntities fetch
