How should unit tests set up data sources when not running in an application server? <p>Thank you all for your help. A number of you posted (as I should have expected) answers indicating my whole approach was wrong, or that low-level code should never have to know whether or not it is running in a container. I would t... | <p>The whole concept is back to front. Lower level code should not be doing this sort of testing. If you need a different implementation pass it down at a relevant point.</p>

Using IN clause in a native sql query <p>We are trying to dynamically generate an IN clause for a native sql query to return a JPA entity. Hibernate is our JPA provider. Our code looks something like this.</p>
