Does multicast transport exist?

[Shimik]

Does multicast transport exist in 5.1? Reliable using JGroups/JRMS or unreliable.
According to this http://activemq.apache.org/uri-protocols.html, one might think it does.
If it does, how can I use it?

Hi Shimik,
    I'm looking for the same info, although I'm currently on 4.1.2.
When I did a code dive, I noticed that there are multicast connectors
(transport & network) although they appear to be unreliable.  My attempts
to use it have been unsuccessful so far.

Good luck,
D.

According to these posts there are others who are looking for the same thing. I can't figure out if it exist or not.

Maybe someone can shade light on this issue.

The second posting's thread states that reliable multicast is currently on the todo list and that JGroups is not an option, because "JGroups is LGPL and slow".

The documentation is misleading. It shouldn't list multicast as one of the transport protocols and definitely not on the main page.

http://activemq.apache.org/ - Supports pluggable transport protocols such as in-VM, TCP, SSL, NIO, UDP, multicast, JGroups and JXTA transports.
