My ant script looks like:
I'm trying to upgrade the Roller 4.0 code base from OpenJPA 0.9.7 to
OpenJPA 1.0 but I'm running into a blocking issue.
The task that we use to enhance our POJOs is locking up
during the build process. There are no error messages or stack traces,
but the CPU goes to about 98% (on my core duo Mac
thanks a lot! i'll check it out!

Netbeans just've added some support for OpenJPA:
http://www.netbeans.org/issues/show_bug.cgi?id=99940. Feel free to try and let
them know what needs to be improved.

Hi Evgeny,
The JPA spec is clear on the concept of a detached instance: the
instance can be used without access to the underlying database or the
persistence context whence it came. The instance can be serialized
and used in a different tier entirely. The instance can be used in a

Actually, you should be able to call
Persistence.createEntityManagerFactory("foo", map), where "foo" is the
name of your persistence unit in a META-INF/persistence.xml file.

They do, but really, all that they are doing is hiding the open EM. In
other words, the objects are not actually really detached yet.

Hi,
Lazy loading is not available for detached entities -- by definition,
they are no longer associated with the database.
You can, however, control whether OpenJPA returns null or throws an
exception when an unloaded field is accessed.
If you want to be able to lazily access a field after a tr

Yes fetch groups are suppored in OpenJPA. So can u give some basic use
