See if you can force Spring to use CGLIB proxies... JDK proxies are interface-based, so unless you are implementing an interface that exposes all of the methods you will interact with (Action interface has no methods, IIRC), then AOP / @Transactional won't work right.
Although, carry on with the Service layer discussion, I agree with that and take my fix as no indication that I would ever try to make an Action transactional (wink). -Wes On Thu, Apr 30, 2009 at 10:41 PM, Mauricio Aniche <mauricioani...@gmail.com> wrote: > Hi Jeroen, > > The problem is that I am not a big fan of services layer.
