First off I have to admit I don't fully understand how JBoss supports clustering in a WAN environment. Basically we are writing a management application where there can be management stations scattered throughout the world and they will communicate via some messaging library over the WAN as well as through a local LAN. We need a robust and highly available messaging platform and JBoss Messaging looks like it will meet our needs but I don't understand the implications over a WAN. Any guidance or advice would be very much appreciated. We have also looked at JGroups but we want to stay with an industry standard if possible for integration purposes.
