Thanks,Vijaya ,but want to know if it is possible to deploy an application adf 12c in jdeveloper 11g.
No.. ADF 12c apps cannot be deployed to jdeveloper 11g as 11g envirounment will not have any libraries of adf 12c shipped and there are chances you may get in to classloader issues.
hope this answers your question!!
Thanks, Vijaya you are answered me
