I have reverse engineered my database and generated domain code with Hibernate Tools. For each table (e.g. tabA), I get a file tabA.java and a file tabAId.java.

How are these supposed to be used? I want to write code like this:

tabA mtab = new tabA();
mtab.setPersonName("Bobby");
session.save(mtab);

However, the table fields are not available in the tabA.java-file, just in the tabAId.java-file. The tabA.java-file just contains the field:

private tabAId id;

with getters and setters.

I have tried to find some documentation on this matter, without success. Anybody how can help explain how these two files relate and how they are supposed to be used?

Sounds to me like you do not have primary keys on your tables. Since there are no primary keys, the reverse engineering tools attempt to use a natural key. Since there is no natural key defined, it will assume that all columns make up a composite key. Easy fix: put primary keys on your tables or mark them as such in the reverse engineering file.

You are absolutely correct! That was the issue - thx!
