Greetings
IHAC who is using Persistence PowrTier EJB app server for on-line trading and stock
updates. The client is a standalone Java application that essentailly logs in and
pulls info from the EJB server. It also must receive stock updates from the EJB
server that is in turn receving updates from the a legacy data source. The question
is, once the EJB beans has recieved updates from the legacy data source (via JMS or
other App server supported messaging system) what mechanism can be used to push the
data to a client acrosss the internet. One option under consideration is using JMS
Topics to do pub/sub push to the client. I believe the JMS Topics are using multicast
underneath (the JMS providers are I should say) and if this is the case, can multicast
span the internet across routers that may not support multicast. If JMS is not an
option what other methods can be used (other than sockets of course). I believe
Weblogic has a proprietary event delivery mechanism as well. Any!
