Good Day,
i am using oracle driver to test a small application and i am getting these Error:
oracle.jdbc.driver.OracleDriver od = new oracle.jdbc.driver.OracleDriver();
properties p = new properties();
p.load("new FileInputStream("c:\\filename.properties");
connection con = od.connect("jdbc:oracle:thin:@localhost:1521:sid",p);
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select user from dual");
while(rs.next()) {
System.out.println(rs);
rs.close();
Error Message is showing at od.connect("url",p);

Hi user,
try to do that:
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public void method() {
try {
     Connection connection;
String driver = "oracle.jdbc.driver.OracleDriver";
String url = "jdbc:oracle:thin:@localhost:1521:Sid";
     Class.forName(driver).newInstance();
     connection = DriverManager.getConnection(url, your_user, your_password);
     PreparedStatement st = connection.prepareStatement("select user from dual");
     ResultSet rs = st.executeQuery();
     while(rs.next()) {
          System.out.println(rs);
     rs.close();
} catch (ClassNotFoundException e) {
} catch (IllegalAccessException e) {
} catch (InstantiationException e) {
} catch (SQLException e) {
}
