Why ServiceMix for EAI Patterns?
ServiceMix provides the servicemix-eip component as a standard JBI-compliant
component. This provides implementations for many of the patterns discussed in
the EAI patterns book. When I first read the EAI patterns book, I was wondering

patterns and diagrams. But as we all agree, patterns are nuggets of guidelines which
we can implement in many ways, using any technology or platform.
