Hello,

ok so this connection worked for a few mins last week, not sure but it has stopped working from this morning. The entity I have created here, I can connect to Oracle Instance through sqlplus using the same credentials.

you are getting null pointer exception because when you are trying to save the connection db connect will validate the connection and it's getting nothing back from sql server.

It could be because of authentication or some other issue. 

can you confirm, if you are using local sql credentials or domain credentials?
