JDBC uses the following format for connection URLs...
jdbc:driver
://hostname
:port
/dbName
From your screenshot, it looks like you’ve missed the ‘//’ characters between the driver and hostname.
Hope this helps.
For everyone who is coming over this question:
In oracle jdbc urls you have to differentiate between service or SID.
With SID the syntax should be as follows:
'jdbc:oracle:thin:@[IP]:[Port]:[SID]'
with service the snytax should be as follows:
'jdbc:oracle:thin:@//[IP]:[Port]/[Service Name]'
