Prevayler is one such (http://www.prevayler.org/), for Java code which can be written in the right style for Prevayler. Although the concept of Prevayler is pretty simple, there is some nice trickiness in the journaling code (in particular, which makes sure that the data has been sent to disk before acting as if the data has been written, without destroying performance).
Prevayler is not the only journaling code you'll ever need (even if you are writing in Java), but I agree that it makes sense to think in terms of journaling libraries rather than each application trying to get this right (and possibly failing in subtle ways).
