How I see it is, in the container you start the transaction and pass to the object that you want to use the object. And then once that object is done, you're container will commit the transaction and handle any of the errors. First step I think would be to handle this straight through with a Database object, and your underlying objects would have to take/use/get the Database object that is created in the IoC container.

Hello, I have quickly checked sources of spring to see how IoC is done with Hibernate, and I thought that maybe trick is passing Spring Transaction to Castor JDO object ... but had just a quick look, and since I know castor only from user point of view...i am not sure if that is the way to go... And as well something like 'hibernatedaosupport' could be created for castor, that wraps Castor's JDO....

Hello, I have thought...... but just thought.... because I am already using Spring at home with hibernate, and since I want To switch my persistence layer, I have sent a mail almost 1 month ago About how to do it.... Got some replies by castor committers to continue discussion on dev list, and that some of castor committers has at some point integrated castor with Spring, though I am not aware of details.. But After that I got an huge workload that brought me away from that Idea...
I would be interested however in participating on that issue however...

Hello all, I was wondering if anyone out there has thought about, or done something with, integrating Castor with an IoC container like HiveMind or Spring. I know there is a big Spring + Hibernate movement out there, and was wondering what the possibilies where for doing something similar with Castor, mainly the JDO part, but there may be room for doing stuff with XML as well.
There is a lot of boiler plate code that goes into a lot of functions when deal with castor. Such as jdo.getDatabase, db.begin, db.commit, etc etc. To me it looks like this could be wrapped up, but I don't have a lot of experince with IoC's yet and have only used HiveMind (which I like quite a bit).
I think having a layer like this would be pretty cool and actually pretty helpful as well. I think another option would be using AspectJ, but thats to non-javaish for me at the moment and a little to Black Magicish. Maybe when it matures a little bit and gets more tool support besides just Eclipse it would be something I would look into.
Any input? Ideas?
Nick,
I've got a lot of experience with Spring and had only just begun to look into integrating Castor with it. I'd love to provide such integration and write all about it in the Castor Live book eventually. But first I need to finish the last three chapters. Let me do that and then I'll have the time to look into Spring integration.
