I come from a background of MoM. I think I understand ESB conceptually. However, I'm not too sure about the practical differences between the two when it comes to making a choice architecturally. Here is what I want to know 1) Any good links online which can help me in this regard. 2) Can someone tell me where it makes sense to use on...
I'm in the market for a good open source network based Pub/Sub (observer pattern) library. I haven't found any I like: JMS - tied to Java, treats message contents as dumb binary blobs NDDS - $$, use of IDL CORBA/ICE - Pub/Sub is built on-top of RPC, CORBA API is non-intuitive JBOSS/ESB - not too familiar with It would be nice if su...
I am trying to find a message bus provider that supports Durable Subscribers and allows me to replay, in order, based on the message timestamp, all messages for a given topic. Futhermore, I would like the message bus to reset each durable consumer's checkpoint when a message arrives late. E.g. Client subscribes to topic 1 at 2009-12-22...

For example, say, is Google using such solution for it's main search engine or to power GMail? What about big websites like Walmart, eBay, FedEx (pretty much a Jav...
I would like to write a application for mobile devices (blackberry and android). Is there a (free) client to connect to a MOM? The MOM should guarantee message delivery even if the connection is closed and reopened. We thought about using jms, but is there a free client that works on these platforms? XMPP could be another alternative. ...

Or do they just fire off when a new alarm happens? My connector polls the subscription every 30 seconds and sometimes doesn't return any a...
Is there a way programatically to find out if the SCOM agent is in Maintenance Mode. ...
I've been trying to figure out exactly what message-oriented middleware is, but haven't been able to find any non-enterprise real world examples that make sense to me. Can anyone give me a clear and easily understandable explanation of what MOM is, and possibly some simple examples of how it's used outside of enterprise? ...
