    Oracle JDeveloper 12C Oracle (JDBC)

      Hi guys,

       

      I recently downloaded Oracle JDeveloper 12c Studio Edition, during the installation there were no errors as it was successfully installed.

       

      I tried to connect to the database via create database connection but I got this error:

       

      Test failed: IO Error: The Network Adapter could not establish the connection (this error was shown after typing the username: hr and password: hr)

       

      As I am new to Oracle JDeveloper, I was following a tutorial and realised that in the tutorial the user was using Oracle JDeveloper 11g.

       

      So I checked Services in the Administrators tools and found that OracleServicesXE was nowhere to be seen.

       

      Could someone please explain what I could do? Is there a download that I must install? As I don't know how to make this work.
