Hibernate should only "see" annotated getters

I have a problem with an EJB3 persistent entity - "User".

I have added a getter (getContact()) which gets a derived piece of information from the object.

On deployment, I get the following error:

Code:

Caused by: org.hibernate.PropertyNotFoundException: Could not find a setter for property contact in class com.fcl.greenfield.entity.

It should NOT be doing this. It's a read-only property. Hibernate should only look at getters/setters which are annotated as database columns. It's interfering!

Is there a way of avoiding this, or do I have to violate standards, and make my method extractContact()?

Found it. @Transient needed.

The Javadocs for the annotations are totally blank, they don't explain what they do AT ALL!

hibernate/cglib looks up only those properties which are specified in your mapping file.
Obviously your User class has no method setContact()

I have no mapping file. I'm using EJB3 annotations to specify which getters correspond to database columns.

I contend that unannotated getters should be ignored.

The "contact" property is indeed read-only.
