[appengine-java] Re: JDO/JPA Snippets That Work - Optimistic Locking With @Version

[Patrizio Munzi]

Hi Max, I've just read your new post and I've got two questions. 1) should we discuss your new posts in this mailing list or in the blog? Since you haven't answer my first question yet, :-P, I'm going to ask my second question in both ways. 2) Before your new post the only way I knew for transaction isolation was using the JDOCanRetryException (or at least we'll use it as soon as the bug fix about it will be released), now we've got also this JDOOptimisticVerificationException. Now, I can imagine the difference between them but I'd like to know what's the best way to deal with both of them. I mean, should we use both of them? Using the JDOCanRetryException mechanism shouldn't be need of the JDOOptimisticVerificationException. We'd be very grateful if you could clarify this out.
