Hi,
This is a small code snippet, i believe this is more than enough...
String url = "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=firstDB)))";
String username= "test";
String password = "test";
String GET_EMPLOYEE_DETAILS = "select name, age from managers";
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
Connection con = DriverManager.getConnection(url, username, password1);
PreparedStatement pstmt =con.prepareStatement(GET_EMPLOYEE_DETAILS );
ResultSet rs = pstmt.executeQuery();
while ( rs.next())
System.out.println(rs.getString("name") + ":"+ rs.getInt("age") );
rs.close();
pstmt.close();
con.close
