Oracle SOA Suite 11g
I've playing around with the new preview of Oracle SOA Suite. Among the new features, Business Events is the most attractive to me and it can be considered Oracle's first iteration towards a complete Complex Event Processing platform based on different technologies of the SOA Suite. Additionally, the implementation of Service Component Architecture (SCA) as part of the SOA Composite Editor is definitely interesting although I am still not convinced of its applicability on Enterprise scenarios.
