Re: Migrating to cayenne 3.1

[John Huss]

First you need to subclass the factory:

public class MyContextFactory extends DataContextFactory {
    @Override
    protected DataContext newInstance(DataChannel parent, ObjectStore
objectStore) {
    return new MyContext(parent, objectStore);
    }
}

Then, create a custom Dependency Injector module:

import org.apache.cayenne.configuration.ObjectContextFactory;
import org.apache.cayenne.di.Binder;
import org.apache.cayenne.di.Module;

public class AppModule implements Module {
public void configure(Binder binder) {
binder.bind(ObjectContextFactory.class).toInstance(new MyContextFactory());
}
}

Then reference your module when creating the CayenneRuntime:

 ServerRuntime localRuntime = new
ServerRuntime("cayenne-MyDomain.xml", newAppModule());
