1. For Oracle JDBC url:

2. Make sure oracle database instance is running on port 1521 and that port is open.

3. Disable the similes.

Is Oralce running locally? Are you using a SID and is it correctly configured?

I am also getting Network adapter error could not establish connection, but I get this error when my internet connection is on, otherwise it connects to oracle properly and all my queries work properly when my Internet is off.
