Entity without table

Hi guys,
I have an entity called ScheduleOperations which refers to entity RefferencePattern .However this RefferencePattern doesnt have table of its own

How to write the hibernate mapping for ScheduleOperations in this case??
Thanks

It depends on the relationships between those two classes. How would you represent it using UML for example? Composition? Association? nary ? unary?

From what you describe, I guess you have something like a component mapping (http://www.hibernate.org/hib_docs/refer ... nents.html) => it will let you put the corresponding columns into the table of the container entity (so, you're obviously forced to have an unary multiplicity to do this).

Good evening everybody

My class mate and me are trying to run hibernate, but we get an error message from the session factory "Sessionfactory error: could no determine type for: java.sql.Connection, at table:CAT_DBCONNECTOR, for columns: [org.hibernate.mapping.Column(CON)].
We do not have a table called CAT_DBCONNECTOR (it is only a class in our eclipse-project) in our database (HSQLDB) and this is why this error message appears.

The solution seams indicated above, but the link does not work and we are a bit stuck here.
So can you please help us, because we are true newbies.

Thank you!

Hi Rickle88,

the document mentioned by batmat is Hibernate reference, Chapter "Component mapping". It can be found here: archived at time of batmat's post or current version.

However, i don't think your problem is really related to this topic. You should probably start a new topic with more info.
