I saw a blog entry that I understood to indicate that runtime enhancement was supported but I've just grep'ed most of the source code and can't find anything about it. Is it still on the wish list or has been implemented but I just can't find it?

hi, this feature is not supported out of box from romaframework now, you can include the runtime enhancement using the datanucleus agent, just adding this:

-javaagent:datanucleus-core.jar=mydomain.mypackage1,mydomain.mypackage2

to your java command line, yo can find the datails here: http://www.datanucleus.org/products/datanucleus/jdo/enhancer.html#runtime

i admit i'm looking for a solution that work out of the box, but i spent a lot of time on it and is quite hard find one that work every time every where. so for now just use the agent provided by datanucleus!

I've been using the most excellent Datanucleus -javaagent feature for
quite some time now with IntelliJ but a few days ago I tried it on
Eclipse but ended up with some 'cyclic reference' exception....

However, I just tried it again and this time I added the package names
to restrict the scope of classes that need enhancing and it now works
under eclipse! Yeehah!

Regards,

Chris
