What's the difference between JBoss ESB and JBoss HornetQ

Question

Çould anyone explain me the difference b/W Jboss ESB and Jboss HornetQ? Do i need Jboss ESB to use JBoss HornetQ?

Answer 1

HornetQ is a Enterprise Grade JMS Messaging System.

JBoss ESB is a Enterprise Service Bus technology that can make use of a JMS Messaging System.

In the case of JBoss there is a bundled technology platform called JBoss SOA Platform that includes an installation of JBoss ESB and HornetQ Messaging into JBoss EAP 5.1.

In short: HornetQ doesn't use JBoss ESB. JBoss ESB can use HornetQ but its not required.
