Oracle SQL Error
I get this sql error every time I try to connect to an Oracle instance using JDBC.
java.sql.SQLException: Io exception:
The Network Adapter could not establish connection
SQLException: SQLState (null) vendor code (17002)
What am I doing wrong?

Does it connect after the error ?. First try to connect from your client to Oracle server using SQL plus client.
Second - Do a tnsping <server name>
This will give you the correct Host name, SID and Port number.
Make sure that your JDBC connection parameters match with the actual connection from TNS output
