In this blog I will walk  you  through from the new features of OSB 12c as well as the difference between OSB 11g and 12c. Following are the differences between OSB 11g and 12c : In the new version Oracle Service Bus (OSB) is renamed as Service Bus.

To perform operations on database, ftp and files, it is no longer required to configure adapters in JDeveloper and copy it to Eclipse, because OSB 12c service is developed using JDeveloper only.
