Hi Sanga,
Hoping the OpenJPA folks have some insight on the error.

Greetings,
I know the problem is that there is no in my persistence XML.
<properties>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema(ForeignKeys=true)" />
</properties>
but I get problems here that in DB :
Table User (number id, varchar name, number address_id). And the
address_id
can be null.
Table Address(number id, varchar description)
I map the User table into entity UserBean for example and set my
addressId
as null because I dont need it.
if i delete in my persitence.xml the "xml fragment upstair (property
fragment)", i will get error message
<openjpa-1.1.0-r422266:659716 nonfatal general error>

org.apache.openjpa.persistence.PersistenceException: Table "User"
has a
foreign key to table "Address" that has not been generated. You
must run
the schema generator on all inter-related tables at once.
i just want to insert and delete into User table using UserEntity
and set
the addressId as null because later addressId can be taken from
another
class who deals with it. (I am working with already existing
application and
db).
Any advice guys to deal with this situation ??
best regards
