I believe the step you missed was creating the JNDI you are using to look up the adapter config by creating an outbound connection pool in the fileAdapter deployment.
Console -> Deployments -> fileAdapter -> Configuration -> (Outbound Connection Pool Tab) -> Click "NEW" enter in the JNDI you are using to reference the fileAdapter you created via your wizard and that is referenced in your BS -> click save (restart the cluster / or application itself).
Let me know if you had already done this or not. I believe you just missed this configuration step!
Best of luck!
I already have the fileAdapter JNDI is already configured in console. The error I am getting is during the deployment
Conflicts found during publish.
