public EntityManager createEntityManager ();
public EntityManager createEntityManager (Map map);

The two createEntityManager methods above create a new EntityManager each time they are invoked. The optional Map is used to to supply vendor-specific settings. If you have configured your implementation for JTA transactions and a JTA transaction is active, the returned EntityManager will be synchronized with that transaction.

Note

Kodo recognizes the following string keys in the map supplied to createEntityManager: kodo.ConnectionUserName kodo.ConnectionPassword kodo.ConnectionRetainMode kodo.TransactionMode kodo.<property>, where <property> is any JavaBean property of the org.apache.openjpa.persistence.OpenJPAEntityManager. The last option uses reflection to configure any property of Kodo's EntityManager implementation with the value supplied in your map. The first options correspond exactly to the same-named Kodo configuration keys described in Chapter 2, Configuration of the Reference Guide.
