TiendaWebApplication virtual int runFreeze(int, char *[],const Freeze::DBEnvironmentPtr & dbEnv)
{
Freeze::DBPtr db = dbEnv->openDB("tiendaWebFs",true);
// Create an object adapter
TiendaWebI::_adapter=communicator()->createObjectAdapterWithEndpoints("TiendaWebService","default -p 10000");
Ice::ObjectFactoryPtr factory = new TiendaWebFactory();
communicator()->addObjectFactory(factory, ProductView::ice_staticId() );
Freeze::PersistenceStrategyPtr strategy= db->createEvictionStrategy();
TiendaWebI::_evictor=db->createEvictor(strategy);
TiendaWebI::_adapter->addServantLocator(TiendaWebI::_evictor,"");
TiendaWebI::_adapter->activate();
communicator()->waitForShutdown();
if(interrupted())
{
cerr<<appName()<<": received signal, shutting down"<<endl;
}
