What is the database exception?

Is the JDBC driver still able to function, or is it returning invalid data?

Anyone database exception like a NOT NULL verification.
I think the JDBC driver is correct. I can''t see any invalid data only the stacktrace that I showed before.

Additional information: It is a Web application running under tomcat.

I have never seen this, and can't see how it could possible occur.

What database/JDBC driver are you using?

It looks like the row being returned from the database is empty, which does not make much sense.

Please include the stack trace of the exception that occurred.

Hi James,
I found the root of the problem, it is related to serialization of BlazeDS (

Solved using a Spring Exception Translator.
