Day 6 - JMS Bindings

The day contained a deep dive in the SCA programming model and references as well as the usual best practices such as:

• Coarse grained interfaces
• Limit network roundtrips
• Don't use WS between different architechtural layers in the same application

Then we dug into JMS and got an introduction to the WPS SIB (Service Integration Bus) which is the messaging bus used by all components in WPS so it serves as the backbone of communication within Process Server. It's a pure Java implementation which is JMS 1.1 compliant. It contains a mediation framework which uses mediation handlers to transform, transcode, reroute, and manipulate messages. The SIB can be set up to communicate with a real MQ installation through an MQClientLink or MQLink. Seen from the perspective of MQ, the SIB is seen as a real queue manager.
