Hello All
In our project we are using JPA2.0 with two persistence units. I have two
persistence manager and able to initialize successfully on IBM WAS. I am
using RSA 8.0 to generate the entities. we have two database one is SQL
server and another on is DB2. My requirement is before calling persist
method on EntityManager i have first choose the EntityManager in other words
how to make sure that Entity/Table belongs to SQLServer or DB2 below API's
are returning false
@PersistenceContext(unitName="MIApplicationSQL")
private EntityManager emSqlServer;
@PersistenceContext(unitName="MIApplicationDB2")
private EntityManager emDB2;
private EntityManager getEntityManager(FwrkDO fnDO) {
EntityManager em = null;
// emSqlServer is an EntityManager for SQL server
// emDB2 is an EntityManager for Db2
//fndo is an entity which need to be validated
Set<EntityType<?>> entities = emDB2.getMetamodel().getEntities();
Set<EntityType<?>> entities2 =
emSqlServer.getMetamodel().getEntities();
// contains method returns false
if (entities2.contains(fnDO)) {
em = emSqlServer;
} else if (entities.contains(fnDO)) {
em = emDB2;
}
// EntityManager.contains also returning false
if (emSqlServer.contains(fnDO)) {
em = emSqlServer;
} else if (emDB2.contains(fnDO)) {
em = emDB2;
}
return em;
}
How to ensure the entity/table is belongs to SQLServer or DB2 server.
