Hi,

I am new to Hibernate.

This is more of a XDoclet issue than Hibernate issue.

I have 3 classes

1. OIDObject.java : generates sequence ID.
2. Error.java extends OIDObject : Superclass
3. WorkRequestError extends Error : Subclass

I am using "Table per Subclass".

Sequence ID generation is working fine.

Problem Description :

When I put @hibernate.joined-subclass and @hibernate.joined-subclass-key tags in WorkRequesError.java, it is not creating "<Joined-subclass>" mapping in superclass mapping file i.e. error.hbm.xml file.

Am I missing something here ?

My mapping file and Java classes are listed below.

Please Help !!!

Thanks

JP

}
}

Code between sessionFactory.openSession() and session.close(): None

Full stack trace of any exception that occurs : No Exception

Name and version of the database you are using : Oracle 9i

Debug level Hibernate log excerpt:

Some progress on this ...

If I move, subclass, WorkRequestError.java in the same package as superclass, Error.java, xdoclet is generating "joined-subclass" mapping. But would not work in separate packages...

Any input ?

Thanks
