[jboss-dev-forums] [Design of EJB 3.0] - EJBTHREE-1844: Retry on rollback

[wolfc]

I've added a function to retry an operation whenever an EJBTransactionRolledbackException occurs. Usually this is because of a resource commit failure, which could be caused by a temporary problem (dead lock / outage).

To configure the retry currently the annotation org.jboss.ejb3.tx.api.TransactionRetry needs to be put either on the bean or on a method.

What I don't like is the fact that the annotation now resides within ejb3-transactions, so I've marked it experimental. Either it should go to ejb3-ext-api, but this would change our api (for the better) or into ejb3-tx-api. Alternatively I could create an ejb3-tx-retry component which would could slot into a runtime.

Also we need to be able to extend jboss-metadata to allow plugins, so that the retry function can be enabled via descriptors.

How do we want to proceed here?
