OJB database store?
Hi,
Just to let you know that I've actually started working on the new RDBMS
store based on the Apache OJB O/R tool. I don't want to duplicate
efforts nor waste my limited time so I just want to make sure this is
going to be useful before I get too deep into it. Is this Ok?
BTW, what package should I put it in, org.apache.slide.store.ojb ?
I see that while most of the stores are located under
org.apache.slide.store the current rdbms stores are in
org.apache.slide.store.impl !

Great!

No, it's not in the OJB CVS repository. I am not even sure the OJB
people will accept the patch, but I hope so. And, yes, it is for the
retry thing to work. We could get this done in Slide as well, but it
would be much cleaner to have it in OJB....

Fine. I need a week or two before I can post anything. I'll set up the
framework and some initial code and then you can jump in!
These conflict exceptions are probably needed to make your latest retry
code work. Is this already in the OJB CVS repository? Anyway, you can
handle that later ;-)

I think this would be great :) I promise I will help where I can!
I have already had a look at OJB and submitted a patch that allows to
map SQL exceptions that are caused by concurrency conflicts like
deadlocks to special subclasses of PersistenceBrokerSQLException. I
have extracted this from the Slide core and adapted it to OJB.

org.apache.slide.store.ojb should be fine, but
org.apache.slide.store.impl.ojb is ok as well.
The org.apache.slide.store.impl.rdbms package is named as such for
historical reasons.
