Recommended ActiveMQ Config for Stomp

[Michael Caplan]

Hi there,

I’m working on tightening up my ActiveMQ config for Stomp only use, and am
trying to refine my config to this end.  There are a couple of points in my
config, and the “Complex Single Broker Configuration (Stomp only)” [CSBS]
(http://activemq.apache.org/user-submitted-configurations.html) that I am
unsure about.  What I am hoping to achieve is a simple single broker, stomp
only, and access limited by IP.

I worked from the base config file bundled with the distro, and came up with
the below.  The config points that I am unsure of include:

•       destinationPolicy (why doesn’t the CSBS example implement this?)
•       persistenceAdapter (why doesn’t the CSBS example implement this?)
•       systemUsage (why doesn’t the CSBS example implement this?)
•       Can I implement a rule that tells the broker that stomp requests are to 
be
only accepted from an IP (or series of IPs)
•       Can I implement a rule that tells the web UI to be restricted by IP as
well?


Thanks for the feedback!

Mike
