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

Pros and Cons

� 5 Possible Tiers of Abstraction� Class� Bean

� Distance from Java� Steep Learning Curve – all new� External Dependency� Bean

� 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� Based on Standards� Out of the Box Functionality� Open Source

� Growing Feature set� Large Support Community
