Quick question which I cannot find the answer to on the BAM page. How reliable is the BAM service? Does it provide a persistent subscription feature like JMS? In critical services where packets are sent and must be processed by a subscriber without losing that information, does BAM take care of this? Is there also a transaction feature to BAM where a message could either be put back into the queue to be retried if transaction fails and rolls back?
it may be that BAM is currently geared towards the chat architecture such as twitter/IM/comet/etc so this may not apply, but I'd like to know the options available. What's the plan for Resin's BAM and JMS implementation? Separate or may be integrated into one? -Chris On Aug 7, 2008, at 8:58 AM, Scott Ferguson wrote: > Resin 3.2.0 is now available at the usual download http://caucho.com/download > .
