[jboss-dev-forums] [Design of JBoss ESB] - Re: Configuration - normalization

[tfennelly]

OK, we're back!  But this time we can say we have truely reached a consensus.  Kurt is going to add his name to this once he comes back from lunch - he promised :-)

So we've finally agreed on an approach that keeps both of us happy.  We had a very detailed negotiation and we're both happy campers now.  This doesn't undo any of the work we've been doing.

The config has 2 main sections - "providers" and "services".  The providers section encapsulates the bus/channel info (we both hate the name "bus" here :-) ).  Basically they're "Bus Providers" and there can be different types - JMS, FTP etc.  The "services" section then defines the services - their Gateway and ESB Aware Listerns, Actions etc.  The listeners reference whatever bus/channel it is that they receive messages on.  Simple as that :-)
