Configuration configuration = new Configuration()
			.addClass(com.cls.clock.TUpdateParameter.class)
			.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect")
			.setProperty("hibernate.connection.driver_class", "oracle.jdbc.OracleDriver")
			.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@"+ databaseHost + ":1521:" + databaseName))
			.setProperty("hibernate.connection.username", databaseUser)
			.setProperty("hibernate.connection.password", databasePassword)
			//.setProperty("connection.pool_size","10")
			.setProperty("cache.use_second_level_cache" , "false")
			.setProperty("cache.provider_class", "org.hibernate.cache.EhCacheProvider")
			.setProperty("cache.use_query_cache", "false") 
			.setProperty("show_sql", "false");		
 
			sessionFactory = configuration.buildSessionFactory();

Mais j'ai l'erreur suivante:

J'ai essayé de jouer avec les paramètres en les changeant de position mais rien ni fait.

Merci à tous

Soit tu mets cache.use_second_level_cache à false et tu ne renseignes pas ni cache.provider_class ni cache.use_query_cache.
Soit tu mets cache.use_second_level_cache à true et tu les renseignes.

Merci pour ta réponse.

nouveau test:

Code:

Configuration configuration = new Configuration()
			.addClass( com.cls.clock.parameter.class )
			.setProperty( "hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect" )
			.setProperty( "hibernate.connection.driver_class", "oracle.jdbc.OracleDriver" )
			.setProperty( "hibernate.connection.url", "jdbc:oracle:thin:@"+ databaseHost + ":1521:" + databaseName )
			.setProperty( "hibernate.connection.username", databaseUser )
			.setProperty( "hibernate.connection.password", databasePassword )
			.setProperty( "cache.use_second_level_cache", "false" );
 
			sessionFactory = configuration.buildSessionFactory();

et j'ai la même erreur:

avec le code suivant:

Configuration configuration = new Configuration().configure("com/cls/clock/hibernate.cfg.xml");
sessionFactory = configuration.buildSessionFactory();

là ça marche

C'est pas du au fait que tu as oublié hibernate devant cache.use_second_level_cache ?
Et si tu supprimes carrément toute référence aux propriétés de cache, puisque tu ne veux pas l'utiliser.

C'est exact, il faut ajouter le mot hibernate devant les propriétés.

Merci à toi
