1. Re: What can cause this transaction error?
nickarls Apr 30, 2013 2:03 AM (in response to als)The message says there is no transaction. This can happen if you use entityManager.joinTransaction() in a POJO with no transaction available. One option might be to @Inject UserTransaction ut; and start a transaction there (might be @Resource-injectable also, don't recall). Or use and EJB.
