JDBC Connection from MAC OS(EL Capitan) to Prebuilt Oracle VM

Question

I must have searched the entire net for a solution but no success. I have installed a DeveloperDay prebuilt Oracle Linux 7.3 form the following site: http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html

I am able to connect to the database through SQL Developer using configurations like

• Connection type : Basic
• Username : scott
• Password : oracle
• hostname : localhost
• Port : 1521
• Service name : orcl

Connection is successful and I am able to query properly. But while trying to connect from jdbc from eclipse I am unable to connect. I am getting various errors for various attempts like

• jdbc:oracle:thin:@localhost:1521:orcl

  Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

• jdbc:oracle:thin:@localhost:1521:orcl12c

java.sql.SQLException: ORA-01017: invalid username/password; logon denied

(username and password is entered as scott and oracle respectively)

• jdbc:oracle:thin:@127.0.0.1:1521:orcl12c

java.sql.SQLException: ORA-01017: invalid username /password; logon denied

Please help to resolve this issue.

Because you try to access to a distance database, you consider VM like it is localhost and this is wrong, in fact it is another machine.

To solve this problem you should to use the IP Address of this VM not localhost, and this not easy you should to make some configuration of your VM you can follow this manuals here:
