Reverse engineered VERSION columns cause ClassCastException
-----------------------------------------------------------
Key: HBX-633
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-633
Project: Hibernate Tools
Type: Bug
Versions: 3.1beta4
Environment: Oracle 8i, ojdbc14.jar
Reporter: Gabor Kincses
Exception in thread "main" java.lang.ClassCastException: org.hibernate.type.BigDecimalType
at org.hibernate.tuple.PropertyFactory.buildVersionProperty(PropertyFactory.java:83)
at org.hibernate.tuple.EntityMetamodel.<init>(EntityMetamodel.java:157)
at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:412)
at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:108)
at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55)
at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:216)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176)
at com.paypal.bdo.test.Hibernate101.main(Hibernate101.java:37)
I guess the code tries to cast the type to VersionType.

[ http://opensource.atlassian.com/projects/hibernate/browse/HBX-633?page=comments#action_22736 ] Ahmeed GUEYE commented on HBX-633: ---------------------------------- So the bug is that when processing a column named VERSION, the tool generates a version tag (<version> ) instead of a regular property tag (<property>).

[ http://opensource.atlassian.com/projects/hibernate/browse/HBX-633?page=comments#action_23462 ] Stephane Landelle commented on HBX-633: --------------------------------------- Hum, quite funny indeed... I'm trying to reverse engineer the spring jpetstore database and I run into the same kind of problem. In this case, the problem is a DATE column named TIMESTAMP. HibernateTool generates a version element with a date type but as org.hibernate.type.DateType doesn't implement org.hibernate.type.VersionType, I get a ClassCastException. > Reverse engineered VERSION columns cause ClassCastException > ----------------------------------------------------------- > > Key: HBX-633 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-633 > Project: Hibernate Tools > Type: Bug > Versions: 3.1beta4 > Environment: Oracle 8i, ojdbc14.jar > Reporter: Gabor Kincses > > > Exception in thread "main" java.lang.ClassCastException: org.hibernate.type.BigDecimalType > at org.hibernate.tuple.PropertyFactory.buildVersionProperty(PropertyFactory.java:83) > at org.hibernate.tuple.EntityMetamodel.<init>(EntityMetamodel.java:157) > at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:412) > at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:108) > at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55) > at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:216) > at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176) > at com.paypal.bdo.test.Hibernate101.main(Hibernate101.java:37) > I guess the code tries to cast the type to VersionType. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira |
