Hello, I have had the same problem recently, when I've forgot to make some changes in applicationContext.xml file. All you have to do is to change the dialect from MySQL to Oracle; here is the place where this has to be made: ... <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop> <prop key="hibernate.show_sql">false</prop> <prop key="hibernate.generate_statistics">true</prop> </props> ... That's all, after this change everything works fine... Greetings, Maciej. Post edited by: maciej.mac, at: 2007/05/20 18:56
