"unmanaged" means the Account object assigned to the ManyToOne field is
new and not yet persistent, removed, or detached.

In your example, can you please try the following and see if it resolves the
issue:
@ManyToOne(cascade=CascadeType.ALL)
@JoinColumn(name = "account_id")
private Account account;
}

We have a critical problem in our application, we have multiple enterprise
applications and we have to use distributed transactions to ensure ACID
operations on entire system.
Our Application server is Glassfish V9 update 5 on SUSE 10 and database is
Oracle 10.2.0.1.0.
The problem is when we use oracle.jdbc.xa.client.OracleXADataSource as JDBC
driver and javax.sql.XADataSource as resource type, we get following error in
persisting an entity with a ManyToOne relationship and it complains the other
side of relationship is unmanaged!!! However the other side of the relationship
(here account entity) is already existed in database and with typical JDBC
driver, no error we encounter. I have tested all other OpenJPA versions but the
problem still exists. I don’t know whether this is OpenJPA issue or JDBC
driver, please share your experience on this matter.

This is our entity classes and simple test case:
public class Voucher {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE ,generator =
"VoucherSequenceGenerator")
private Long id;
@ManyToOne
@JoinColumn(name = "account_id")
private Account account;
}
public class Account {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator =
"AccountSequenceGenerator")
private Long id;
}
Account account = entityManager.find(Account.class, 215L);
Voucher voucher = new Voucher();
Voucher.setAccount(account);
entityManager.persist(voucher);
