[news.eclipse.rt.eclipselink] Fixed String or Oracle CHAR

[nic@xxxxxxxxxxxx (Nick)]

I'm in the process of porting an application from Toplink Essentials to 
eclipselink because we need some of the new features or extension of 
eclipselink, but we encounter a snag...

All things considered, setup and etc, a SessionCustomizer that looks like 
below that will handle CHAR columns doesn't work on eclipselink anymore? 
Or am I missing something?


Thanks,
Nick


public class OracleSessionCustomizer implements SessionCustomizer {

public void customize(Session session) {
session.getEventManager().addListener(new OracleSessionListener());
//set the default for the columns.
session.getLogin().setDefaultNullValue(String.class, " ");
session.getLogin().setDefaultNullValue(Integer.class, 0);
session.getLogin().setDefaultNullValue(Long.class, 0);
}

class OracleSessionListener extends SessionEventAdapter {
@Override
public void postAcquireConnection(SessionEvent event) {
Connection conn = ((DatabaseAccessor) event.getResult()).getConnection();
OracleConnection oconn = (OracleConnection) conn;
oconn.setDefaultFixedString(true);
}
}

}

The same SessionCustomizer will work in Toplink flawlessly, where the PK's 
are CHAR's:

For example using find:
   pk.setCol1("XYZ");
   pk.setCol2(" "); <--- a single space
   EntityA entity = em.find(EntityA.class, pk);

For example using persist:
   EntityB entity = new EntityB();
   entity.setCol1("XYZ");
   entity.setCol2(null); 
   em.getTransaction().begin();
   em.find(entity);
   em.getTransaction().commit();
eclipselink will not insert spaces but instead nulls
