When trying to connect or deploy from JDeveloper 12.2.2 to our Oracle Fusion Middleware 12.2.1 domain in the Amazon EC cloud I keep having connection problems. Contacting the consoles is not a problem, however extending the IDE Connection results in this error:

t3://127.0.0.1:7011: [RJVM:000575]Destination 127.0.0.1, 7011 unreachable.; nested exception is:
java.net.ConnectException: Connection refused: connect; [RJVM:000576]No available router to destination.; nested exception is: java.rmi.ConnectException: [RJVM:000576]No available router to destination.Dec 08, 2015 9:50:35 AM oracle.tip.tools.ide.soabrowser.LogUtil logStackTrace

And deploying an artifact to the server results the same

Weblogic configuration

I couldn’t find anything regarding the error on Oracle Support, but luckily my collegue Daljit Singh had the answer. Since the Amazon EC2 uses a public IP (which we use to connect to the admin server) the internal passthrough to the Managed Servers fails. To solve this we should use the Weblogic “external listen address” configuration. The external listen address and port are used to support Network Address Translation (NAT) firewalls. These should match the IP address or DNS name that clients use to access application on the server.

Go to the Weblogic console -> Environment -> Servers -> Managed Server -> Configuration -> General -> Advanced

Make sure the public ip-adres is stored in the External Listen Address here Read the complete article here.
