Are applications built with earlier releases of Oracle JDeveloper compatible with Oracle ADF?
Absolutely. Oracle is strongly committed to upward compatibility between earlier JDeveloper releases and the JDeveloper 10g Release 2 (10.1.2.0.0) production release. Applications developed using the BC4J, UIX, and JClient frameworks in previous releases are compatible with Oracle ADF in JDeveloper 10g and can immediately benefit from all of the visual development features detailed above. Applications developed using ADF in JDeveloper 10g (9.0.5) can be opened, compiled and run in JDeveloper 10g Release 2 (10.1.2.0.0) with no migration issues. In addition to hundreds of external customers, over 2000 internal applications developers in Oracle’s E-Business Suite division have used Oracle’s existing frameworks since 1999 to deliver self-service, Web-based business applications on the J2EE platform. While the Oracle JDeveloper 10g design time has evolved considerably to provide an even more end-to-end visual and declarative experience, all the core concepts will be familiar to existing use
