query.getResultList() throws ClassCastException

I modified the example code to include an index on the Point class like so:     @Index(members={"x","y"}) Then when I run the following query:     TypedQuery<Point> query = em.createQuery("SELECT p FROM Point p where p.x <= :x and p.y >= :y",         Point.class); I get the exception at the end.  I do not get an exception if I: Bug Version: 2.3.0 Priority: Normal Status: Fixed Replies: 3 Type:  Bug ...

Mapped By Fetch is very Slow

Well ! I think i pointed out a HUGE performance issue with mapped-by attribute (yeah again :( ). Here is the test case : 1- Create 100 000 entities with for each 1 entity with @OneToOne(mappedBy attribute) 2- Retrieve only 10 000 for testing 3- Wait ... On my AMD FX 8350, it took 60s Now, go the MyEntity class and remove "mapped-by". You obtain 1 second max of query fetch. ... faster but will require updating both sides on every change (keeping them synchronized). ObjectDB Support ...

JDO sequences from ORM file

I want to use sequences in JDO without using annotations. Normally this is done with a package-X.orm file, where X is a value passed to the PersistenceManagerFactory as the value of property "mapping". I'm encouraged to see that the JDO zip that comes with ObjectDB includes the DTD/XSD for this type of file, though I can't see a mention of it in the manual. #1 2013-03-12 17:07 I want to use sequences in JDO without using annotations.

Mysterious "Attempt to persist a reference to a non managed instance" error

I've been working with ObjectDB for the past several months, and it's behaved pretty much as expected. I made a few modifications to a working set of classes today, and it's started throwing exceptions at commit time. I've stripped it down to a  set of files that seem to be of trivial complexity, but it's still failing. It involves two entities, Index and Ostrich. The thing to note is that the Index structure is recursive through maps; but that's never caused any problem for me in the past. #1 2011-06-08 20:51 I've been working with ObjectDB for the past several months, and it's behaved pretty much as expected.

Server crash - Mismatch client-server protocol prefix

We've been having a problem where our ObjectDB server goes unresponsive every 2 days or so.  I've reviewed the server-side logs, and there are no events logged shortly before the crash.  Once the server gets in this state, it is unresponsive to bin/server.sh restart; I have had to reboot the entire server on which it's running.  The only recorded symptom is a client-side error (which fortunately gets auto-mailed to me): ... cause of this server problem? Maybe both are result of a change in your system or upgrading an ObjectDB version? ...

Pessimistic Lock Timeouts setting

Hi,   I realise that JPA2 doesn't necessarily define a standard API way for Lock Timeouts. However, there is a standardised query 'hint' that can be setup to make the underlying DB lock a record for a specific time. The hint property is: "javax.persistence.lock.timeout" ... - it will help. Notice, however, that the new change doesn't eliminate these exceptions - when the timeout is exceeded ...
