Exception while connecting to an Oracle database

[Steli Niculescu]

I have to do a small JDBC program that works with an Oracle 10g express edition installed on my computer.
I downloaded the 10.2.0.4 driver (ojdbc14.jar) from here, and i have the
following code :

 public class OracleConnection {
	static final String DB_DRIVER = "oracle.jdbc.OracleDriver";
	static final String DB_URL = "jdbc:oracle:thin:system/system@//localhost:1521/orcl"; 
	
	
	private Connection conn;
	private Statement st;
	
	public OracleConnection() {
		try {
			Class.forName("oracle.jdbc.OracleDriver");
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		}
		try {	
			conn = DriverManager.getConnection(DB_URL, "system", "system");
			st = conn.createStatement();
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}  

I get the exception
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
, even if the service is started.

What am i doing wrong?

you should use driver oracle.jdbc.driver.OracleDriver

since you are passing user name/password as arguement so no need to include same in URL

static final String DB_URL = jdbc:oracle:thin:@localhost:1521:orcl;
