jdbc uses the tcp/ip protocol. This requires a listener to be configured and running. Either you didn't configure and start the listener at all, or you configured it incorrectly and your client can't find it.
Using the net8 assistant in the Oracle Network Administration group you can configure a listener.
The general admonition to read installation manuals *before* starting to hack away applies.
