What you're seeing is whitelist violations. These are APIs which may be perfectly fine in an on-premise implementation, but are not compatible with the Java Cloud Service (JCS). See http://docs.oracle.com/cloud/CSJSU/dev_app.htm#BCEEFEBF for more information about the JCS whitelist. In particular, I see violations in your error due to direct SQL access, non-blocking IO, and so on.
To deploy your application to the JCS, you'll need to remove these APIs and dependencies. You can also use the whitelist tool included with the Cloud SDK to check your application before you attempt to deploy it to the cloud.
Hope that helps!
