Weblogic 12c only supports ADF 12c (available in JDeveloper 12c)
Should we use 11G instead of the 12C MichaelK?
If you're developing in JDeveloper 11g, then you'll need to deploy to Weblogic 11g.
I was thinking that WLS 12C supports all 11g versions of deployments,
have you read about this somewhere from oracle sites? please share?
Here is some useful information from WLS 12C guide
WebLogic 12c has support for many IDEs. WebLogic already supports JDeveloper
184.108.40.206, but will come out with 220.127.116.11 later on. However, anyone developing
applications using WLS 18.104.22.168 can deploy them to WLS 12c.
