Hello, I’m doing a proyect for college using Hibernate and Eclipse. I have a superclass and a subclass. The subclass are also conect whit a diferent class. When I try to conect the subclass I get this error: Could not get constructor for org.hibernate.persister.entity.UnionSubclassEntityPersister . …

HBM mappings are considered deprecated by now. Try with annotations since they are better supported. Meanwhile, you can also open a Jira issue as it sounds like a bug.

Thanks for the answer. Unfortunately the professor want us to use hbm.

Try to replicate it with this test case template: http://in.relation.to/2016/01/14/hibernate-jpa-test-case-template/

Try to upload the replicating test case and share the link here so we can take a look on it.

This is all the Failure Trace javax.persistence.PersistenceException: [PersistenceUnit: templatePU] Unable to build Hibernate SessionFactory at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.persistenceException(EntityManagerFactoryBuilderImpl.java:1249) at org.hibernate.jpa.boot…

The exception tells exactly what you have to do. org.hibernate.PropertyNotFoundException: Could not find a getter for seccion_colectivo in class datos.TarifaColectivo

Yes, but i have that getter. In the code that I posted shows the getter and setter. And I dont have a variable call seccion_colectivo

If you generated the DB schema manually, it might not be what Hibernate expects. Try comparing yours with the one generated by hbm2ddl=auto.

I have already done it, what do I do with the Failure Trace?. I’m sorry but I’m new with this.
Thank you.
