Connecting to an Oracle Database</h3>
This example uses an Oracle JDBC driver to connect to an Oracle
database instance located at <code>128.0.0.0:1521</code> with an sid called
<code>mydatabase</code>.
<pre>
Connection connection = null;
try {
// Load the JDBC driver
String driverName = "oracle.jdbc.driver.OracleDriver";
Class.forName(driverName);
// Create a connection to the database
String serverName = <font color="#0066ff"><i>"127.0.0.1"</i></font>;
String portNumber = <font color="#0066ff"><i>"1521"</i></font>;
String sid = <font color="#0066ff"><i>"mydatabase"</i></font>;
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String username = <font color="#0066ff"><i>"username"</i></font>;
String password = <font color="#0066ff"><i>"password"</i></font>;
connection = DriverManager.getConnection(url, username, password);
} catch (ClassNotFoundException e) {
// Could not find the database driver
} catch (SQLException e) {
// Could not connect to the database
}
