I am having a hard time connecting to the database instance using "Cloud Connections," in SQL Developer.
I am using the information found in here: http://docs.oracle.com/cloud/CSDBU/develop.htm#BABDBHJA to connect to my cloud-service, but all I get is an error:
"Authentication Failed Invalid resource owner credentials."
I am positive that I am using the same username and password as when logging in to could.oracle.com.
Apologies for any difficulty you have been having.
I would start by reviewing the white paper on data movement. My guess is that you have not defined an APEX user with SQL Developer privileges (yes, I know the process could be more clear - it's getting there.)
You can find the white paper here - http://www.oracle.com/technetwork/database/database-cloud/public/data-movement-wp-1844121.pdf. Please make sure you follow all the steps properly, for both initialization and the actual connection.
Hope this helps.
