Adding ids to my services does not help. The problem occurs when
HibernateModule is trying to contribute the default HibernateConfigurer, but is
unable to look it up, because it does not specify which one is the default.
This is the code from HibernateModule:
public static void
contributeHibernateSessionSource(OrderedConfiguration<HibernateConfigurer>
config, HibernateConfigurer defaultHibernateConfigurer) {
config.add("Default", defaultHibernateConfigurer);
config.addInstance("PackageName", PackageNameHibernateConfigurer.class);
}
Of course if there is only one HibernateConfigurer implementation then there is
no problem.
