Question marks in EJB-QL logging

[vk101]

Is there a way to instruct Hibernate to output the actual inserted values in the logging output rather than question marks for each query parameter? (Or is this a security measure, so that sensitive information like passwords don't show up in log output?)

By the way, this is for EJB 3.0

Thanks.

In persistence.xml, I've set:

<property name="hibernate.show_sql" value="true"/>

But this doesn't seem to make any difference...what's the solution?
