Messaging
Just ran into a problem where some mutlicast tests were failing on a linux box and I could not figure out why. Did a little bit of research and found out that you may need to add a route for it first. So if you have this problem try running:
route add 224.0.0.0 netmask 240.0.0.0 dev eth0
or if you have an older version of linux like me:
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
Nice to see the new year starting off right. I Noticed this post over at the eaimatrix.com:
A plethora of message queuing products exist in today’s EAI market, all aimed at providing solutions to the problem of application integration. Few can however lay as much claim to fame as ActiveMQ, an open source Message Broker and JMS/Enterprise Integration Patterns provider which is licensed, developed and distributed under the open source Apache emblem. ActiveMQ provides support for Cross Language Client and Protocols as well as a powerful messaging broker which is supported in Java, C, C++, C#, Ruby, Perl, Python, PHP.

Late notice.. but James and I are doing an ActiveMQ Webinar in an hour and half. Sign up for it and let us know what you thought about it.
You have to checkout this great InfoQ Article on ActiveMessaging. It’s an outstanding writeup on how to use ActiveMQ from Rails. I think this is just another sign that STOMP is gain momentum.
OMG, James is at it again! He whipped up the new StompConnect project at a blink of an eye. Firstly, let me introduce you to Stomp. Stomp was designed to be a super simple wire protocol for clients to talk to Message Oriented Middleware (MOM), like ActiveMQ. Since the protocol is text based and simple to implement, multiple language clients and servers were created with little effort.
And now thanks StompConnect, every JMS compliant MOM in existence (which is like almost all of them) can now be talked to using Stomp! This is a huge deal since the wire protocol for most JMS servers is proprietary and and getting a pure language client for any given mom was either difficult or impossible!
