Getting org.hibernate.MappingException for basic Hibernate annotations application ---------------------------------------------------------------------------------- Key: ANN-768 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-768 Project: Hibernate Annotations Issue Type: New Feature Affects Versions: 3.3.0.ga Environment: Hibernate 3.3, MySql 5, Eclipse 3 Reporter: Mandar Shukla Hi, I'm trying Hibernate annotations program along with a business object having 4 attributes. I referred one of the online tutorial and created BO class with annotations, HibernateUtil.java, hibernate.cfg.xml, and .java with main method in it for execution. Everything compiled successfully in eclipse but while executing I got below mentioned exception: Exception in thread "main" org.hibernate.MappingException: Unknown entity: com.flylite.ticketing.model.FlightMaster at org.hibernate.impl.SessionFactoryImpl.getEntityPersister(SessionFactoryImpl.java:557) at org.hibernate.impl.SessionImpl.getEntityPersister(SessionImpl.java:1342) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:98) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:187) at org.hibernate.event.def.DefaultSaveEventListener.saveWithGeneratedOrRequestedId(DefaultSaveEventListener.java:33) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:172) at org.hibernate.event.def.DefaultSaveEventListener.performSaveOrUpdate(DefaultSaveEventListener.java:27) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:539) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:527) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:523) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.hibernate.context.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:318) at $Proxy9.save(Unknown Source) at com.flylite.ticketing.application.TestFlightManager.main(TestFlightManager.java:23) I followed all the steps as per given in tutorial apart from @Table (name="") as we have to use appliesTo in latest version. I doubt (I may be wrong) on @Table(appliesTo="") tag, as I tried similar program couple of months back with lower version of Hibernate where tag was @Table(name=""), and it ran successfully. Please helpe me in this issue. Let me know in case I need to upload my files.
