Does this JMS implementation have a mechanism to get around a chained group of firewalls? What I mean is say I've got several JMS clients/servers (one per JVM) scattered behind a chain of firewalls as so:
JVM #1 ----> Firewall #1 --> JVM #2 --> Firewall #2 --> JVM #3
Obviously let's assume both Firewalls allow traffic back and forth. But JVM #1 cannot directly connect to JVM #3 b/c of the chained firewalls.
Is there a way to send a message from JVM #1 to JVM #3 by having JVM #2 act as a "router"?
www.swiftmq.com has functionality like this but they aren't open source.
I guess a clearer ascii-art diagram would look like this to imply traffic can go both ways:
JVM #1 <----> Firewall #1 <--> JVM #2 <--> Firewall #2 <--> JVM #3
You can achieve this routing topology by using the clustering feature of UberMQ.
If you set up a clustering connection between servers 1 and 2 and servers 2 and 3, messages published at any node will propagate to the other nodes in the infrastructure.
Refer to the user guide for details on how to set this up.
