You'd need to create an @Unwrap component to perform the actual datasource JNDI lookup.  Then you can directly inject it.  Or, you can use an EJB3 component and use the @Resource annotation to get the data source.   But, I'd recommend trying to use the JPA functionality.

Thankyou very much for such a deep answer, it's very helpful. I'll check all these topics shortly :)

Our transactions are all against the same database (if using the same datasource in JPA and in pure JDBC, I don't think we'll have any problem, right?). The only problem is JMS, but I guess it's also covered by what you said and by marking a given method @Transactional, all the JMS operations performed within the boundaries of that method become part of the same transaction.
