I'm using Hibernate/JPA to make transactions with a DB.
I'm not the DBA, and a client consumes my application, a RESTful web service. My problem is that the DB is altered (not very often, but it still changes).

The exception is difficult to translate and read from the log, because it has nested exceptions and consists of a lot of text: like I said, very difficult to understand.
I want to know if it's possible to handle exceptions on entity level, throwing maybe a customized exception.
I thank your patience and help in advance.
PD This is the structure of my test app, validating that two fields are equal:
