You guys
probably have more to worry about right now, with RC1 and all,
but:
A while
back there was a thread regarding the whole 'multiple instance detection' thing
- where the problem of managing multiple listeners vying for the same port was
discussed (JNDI, RMI, etc).
Was there
any resolution or direction? This is of interest to me as we do often have
multiple JBosses running on a single box (to make it more challenging - we share
a box with another group that has pure RMI apps running on
it..).
One of
the options was a 'port manager' that would (if I understand) forward traffic
(like a proxy) to the correct port for the requested
service.
1) To do
this, I imagine the 'port mgr' would have to be able to sniff the incoming
bytestream and determine the requested service by interrogating the content.
This imposes the restriction that only one instance of a service (service being
wire protocol - JNDI, HTTP, RMI, etc) can be routed, since there probably would
be no unambiguous way to differentiate between two HTTP streams (for
instance).
2) The
port mgr (MBean?) would somehow need to be aware of the 'real' ports being used
within the JBoss process space by the managed services. Would the MBean
Notification mechanism suffice? Where each MBean that owns a "managed" port
would send a notification with the port/s onwhich it it is listening. Or,
as (I think) Marc suggested, a P2P solution like JXTA (which may be a better
solution than JMX Notifications?). Or a config file (less than optimal,
IMO).
Thoughts?
I would
definitely be interested in contributing on this. Or maybe no one cares about
this one anymore. :-)
