FOD or Fusion Order Demo is the platform to learn any new Oracle product, I had used it while learning 10gR3, also AIA2.0, and now for 11g. I downloaded the FOD from here, the packaged deployment scripts were great and it just went through besides few hick-ups, tips here
However I couldn't execute the Order-booking demo end to end (some or other errors crop up oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation, or Caused By: javax.xml.soap.SOAPException: Message send failed: Connection refused), I could run the composite and played around em to learn the essential new concepts.
So from 10gR3(weblogic-based), 11g is much different and many important changes, let me try summarize some
1. Earlier we were creating 3 schema (orabpel, oraesb, oraowsm), now it’s more - mds, soainfra, bam and user messaging. MDS is the new thing, which is the metadata storage for all composites.
2. The terminology has changed, In one soa_server there are 4 service engines bpel, mediator (earlier esb), workflow and rules. The same server also has b2b, owsm. The bam server is separate and that’s new Java version.
3. The em is completely new, its shows all the composites, there instances, traces, component traces etc. I couldn't find test screens for components, its there at composite level. Admin stuff by right clicking on soa_infra.
4. Of course the whole idea of composite is new, and a composite has 3 parts service, components and References. So a lot of new config files, deployment fils etc. Complete new composite editor in JDev11g.
5. New frameworks around EDN (even driven networks), SDO (Service Data Objects), Spring etc. to make coding a different experience.
More details as and when I work on them, for now 11g looks just great!
