Here is the My Guice Module that I created. It looks like the one in the
archetype. Do I need to bind every DAO? So that then I need to inject the DAO
when it is needed?
public class AppModule extends AbstractModule {
/* (non-Javadoc)
* @see com.google.inject.AbstractModule#configure()
*/
@Override
protected void configure() {
bind(Initializer.class).asEagerSingleton();
//warp persist stuff
install(PersistenceService.usingHibernate()
.across(UnitOfWork.REQUEST)
.transactedWith(TransactionStrategy.LOCAL)
.buildModule());
// hibernate stuff
// default values from development
String connectionUrl = "<the url>";
String username = "<the username>";
String password = "<the password>";
try {
InitialContext context = new InitialContext();
connectionUrl = (String)
context.lookup("java:comp/env/hibernate.connection.url");
username = (String)
context.lookup("java:comp/env/hibernate.connection.username");
password = (String)
context.lookup("java:comp/env/hibernate.connection.password");
} catch (NamingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// annotation and xml
final Configuration config = new Configuration().configure();
config.setProperty("hibernate.connection.url", connectionUrl);
config.setProperty("hibernate.connection.username", username);
config.setProperty("hibernate.connection.password", password);
config.setProperty("hibernate.current_session_context_class",
"managed");
bind(Configuration.class).toInstance(config);
//dao stuff
// DO I NEED TO DO THIS FOR EVERY DAO OBJECT?????
bind(AccountDao.class).to(HibernateAccountDao.class);
bind(CountryDao.class).to(HibernateCountryDao.class);
bind(LanguageDao.class).to(HibernateLanguageDao.class);
bind(TerritorySalesCodesDao.class).to(HibernateTerritorySalesCodesDao.class);
bind(RegionSalesCodesDao.class).to(HibernateRegionSalesCodesDao.class);
bind(CountrySalesCodesDao.class).to(HibernateCountrySalesCodesDao.class);
bind(AccountTypeDao.class).to(HibernateAccountTypeDao.class);
bind(AccountAuditDao.class).to(HibernateAccountAuditDao.class);
}
@Singleton
public static class Initializer {
@Inject
Initializer(com.wideplay.warp.persist.PersistenceService
service) {
service.start();
}
}
}

Jeffrey,
I expect the changes you made to the Guice Module are the reason why the
session is null, could you paste in the contents of it.
