I try to develop a restful service application. I use weblogic 12c. I have already made application server configuration. When I run to the server server is running. (I can check on the browser http://localhost:7101/console . I can see the Weblogic panel). I already made Artifact configuration for deploy the application. When i try to deploy, i see this error : Artifact RestTestArtifact: Server is not connected. Deploy is not available.
