Testing loading Oracle JDBC driver ... Failed:

Testing the Oracle Home located at C:\app\oracle\product\11.2.0\instantclient-basic-nt-11.2.0.4.0\instantclient_11_2
Testing client directory ... OK
Testing loading Oracle JDBC driver ... Failed:
C:\app\oracle\product\11.2.0\instantclient-basic-nt-11.2.0.4.0\instantclient_11_2\jdbc\lib\ojdbc6.jar is not a valid jar file
I downloaded and extracted the instantclient-jdbc-nt-11.2.0.4.0 zip file from Oracle Technology Network, several times. Still, receiving the same odd error message from Oracle SQL Developer Version 4.0.1.14 test. The ojdbc6.jar file was extracted into the instantclient_11_2 subdirectory, not the lib subdirectory. There is no jdbc or lib subdirectories. Where in configuration is the jdbc and lib subdirectories defined? I need Oracle SQL Developer 4 to look in the instantclient_11_2 subdirectory.

Hi,
...is not a valid jar file
This message is quite misleading. It is not due to a corrupt download. If in Database > Advanced > Use Oracle Client > Configure... you select
Client Type: Oracle Home Client Location: <point at an Instant Client>
then click on Test... this error will occur. Instead you need to select
Client Type: Instant Client
