DriverManager throws this error when it tries to get a connection with invalid URL. Make sure your URL is valid. Things to checkout:

1. Port: Oracle db runs on 1521. (note: don't confuse yourself with webport of oracle, which can be any other port as in your URL 1158).
2. DB name: Get the db name from Oracle Web UI: (home->adminIstration->aboutdatabase->settings)
3. URL format: "jdbc:oracle:thin:@localhost:1521:YourDbName"
