Re: SQL-92 subscription with Headers exchange on C++ broker

2009-02-16 Thread GS.Chandra N
That would be really cool Jonathan. The major reason i fear to take the multiple subscriptions route is due to fears of performance degradation. If i can make do with a single subscription, which performs better than equivalent multiple subscriptions, i could connect more clients to one server (p

Just saw a this https://fedorahosted.org/moksha/ It uses Qpid, and allows you to create live widgets receiving data from an AMQP broker. Uses that qpidd python client. One of the widgets allows you to chat over via a web widget over AMQP, via qpidd to any IRC / XMPP service. Fun to see what

I was poking around the code, becuase I am interested in exposing an EJB as a QMF Agent. In looking at the code, it appears that QMan is more geard to exposing other agents to java code as JMX so as to build JMX consoles. Is that correct? If so, has there been any work on exposing Java Agents
