Santa wants to view RSS feeds from Google Reader and TechCrunch together for Christmas, but they are in different formats; the document explains creating an integration between the feeds using an Enterprise Service Bus (ESB) built with Java, Apache Maven, Apache Camel, Spring, and running on Apache ServiceMix and Apache Karaf as part of a FUSE installation to aggregate the feeds into a single format.

JBI/EIP – Mmmm, tastes delicious!

2. Santa has a problem, just before Christmas!
• He uses RSS feeds
• Google reader provide a public feed of his shared
articlesarticles
• Tech Crunch provide their public feed through
feedproxy
• Santa needs to view both feeds together, but they
have different formats!

4. Recipe Ingredients
• 1 portion of Java, J2SE 6 is best

• 1 portion of Java, J2SE 6 is best
• 3 spoons of Apache Maven, this
will be for building
• 1 tin of already prepared
Enterprise Service Bus (ESB),
FUSE will do fine
Note: FUSE contains
• Apache ServiceMix
• 1 cup of Enterprise
Integration Patterns (EIP),
Apache Camel is preferable
• 5oz of Spring bean container,
helps everything blend well
• Apache ServiceMix
• A healthy amount of Service Oriented Architecture
(SOA)
• 2 dashes of Java Business Integration (JBI)
• 10g of Open Services Gateway Initiative
(OSGi), Apache Karaf mixed with Eclipse
Equinox should be in the FUSE tin
