I don't know the answer to this question, but if you are just looking
for quick simple annotation scanning code, I suggest you take a look
at xbean-finder.

I think that OpenJPAEntityManagerFactorySPI.addLifecycleListener() is

Thanks Patrick.
Background:
The OpenEJB JPA based CMP engine is a wrapper around an
EntityManger. The engine is designed to get out of the way of the
JPA implementation so the performance is only a function of the JPA
implementation. In the engine we do not have a cache or beans or
even the entity manag

When I have a complex id within an unenhanced MappedSuperClass, I get a NPE

ClassMetaData.getField(int) does not take unenhanced MappedSuperclass fields

Failing tests would be swell -- just make the test name be 'xtestFoo'
or something so that we don't pick it up.
The permanent lazy loading problem is
add any schema elements that don't exist and then delete all rows
from all mapped tables, do:
openjpa.jdbc.SynchronizeMappings:
buildSchema(SchemaAction='add,deleteTableContents')

Reading the archives it sounds like drop and recreate table support
was added along with support for clear tables. Unfortunately, I
