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

6. Cooking with Apache Maven

14. Pros and Cons
5 Possible Tiers of Abstraction
Class
Bean
Distance from Java
Steep Learning Curve – all new
External DependencyBean
EIP Route
Service Unit
Service Assembly
High Reusability
Rapid Development and Deployment
Scalable and Clusterable
Configurable and Extendable
Monitoring and Logging tools
External Dependency
Working with bugs/issues
Over flexibility = Excessive Configuration
Debugging more difficult
Loose typing more prone to error
Abstraction worsens Performance?
Monitoring and Logging tools
