This dialog notifies you of a mismatch between the SOA or Service Bus project mode and the server domain.
If the server is in a Classic domain, contact your server administrator to move the server into a Reference Configuration domain. Similarly, if the server is in a Reference Configuration domain, enable the Reference Configuration settings for your project in JDeveloper:
From the File menu, select Tools, then Preferences
Select Reference Configuration Settings, then Enable Reference Configuration settings in adapters.
You can click OK and deploy the project even when there is a configuration mismatch. Deployment will proceed as normal and any Reference Configuration properties set in adapters will be ignored by the domain.
