I have checked and double checked that that class tfeatureAttribute has an hbm.xml file, a persistance class and a DAO. It is referenced in multiple many to one mappings in the other hbm.xml files and the master hibernate.config.xml class….. so what’s the problem???

I used reverse engineering and checked the include all forward and backwards checkboxes, so it brought in a whole ton of mappings.

denma,
Can you give us some more information on this?
1. Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Detatils>
2. What is the verion of Hibernate that you are using?
3. Are there any many-to-many mappings defined on your table?
Can you go through the following links and check if they are related –
1. https://forum.hibernate.org/viewtopic.php?p=2271721&sid=755ae857b0801e0cff7bb911baf908f0
