Dear my friends...

I have some problems in compiling my code. Please tell
me where the mistakes... 

Here is the error message :

psubroto@susefujitsu:~/arsip/proyek> javac
LoadDriver.java
LoadDriver.java:29: cannot resolve symbol
symbol  : class Statement
location: class LoadDriver
                        Statement stmt = null;
                        ^
LoadDriver.java:30: cannot resolve symbol
symbol  : class ResultSet
location: class LoadDriver
                        ResultSet rs = null;
                        ^
2 errors
psubroto@susefujitsu:~/arsip/proyek>

And this is my code:
====
import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.SQLException; 

// Notice, do not import com.mysql.jdbc.* 
// or you will have problems! 

public class LoadDriver { 
    public static void main(String[] args) { 
	
        try { 
            // The newInstance() call is a work around
for some 
            // broken Java implementations

           
Class.forName("com.mysql.jdbc.Driver").newInstance();
			System.out.println("The driver was loaded
succesfully.");
        } catch (Exception ex) { 
            // handle the error 
			System.out.println("The driver could not be
loaded.");
		}
		
		 try {
            Connection conn =
DriverManager.getConnection("jdbc:mysql://localhost/amt?user=root&password=prabumas");
          
            // Do something with the Connection 
            System.out.println("Connection has been
built");
			// Doing select Query
			// assume conn is an already created JDBC
connection
			Statement stmt = null; 
			ResultSet rs = null; 

			try {
				stmt = conn.createStatement(); 
				rs = stmt.executeQuery("SELECT foo FROM bar"); 

			// or alternatively, if you don't know ahead of
time that 
			// the query will be a SELECT... 

			if (stmt.execute("SELECT foo FROM bar")) { 
				rs = stmt.getResultSet(); 
			} 

			// Now do something with the ResultSet .... 
			} finally { 
			// it is a good idea to release
			// resources in a finally{} block 
			// in reverse-order of their creation 
			// if they are no-longer needed 

		if (rs != null) { 
			try {
				rs.close(); 
			} catch (SQLException sqlEx) { // ignore } 

			rs = null; 
			}
		}
				
		if (stmt != null) { 
			try { 
				stmt.close(); 
			} catch (SQLException sqlEx) { // ignore } 

				stmt = null; 
			} 
		}
		}	
  
		  } catch (SQLException ex) {
            // handle any errors 
            System.out.println("SQLException: " +
ex.getMessage()); 
            System.out.println("SQLState: " +
ex.getSQLState()); 
            System.out.println("VendorError: " +
ex.getErrorCode()); 
			}
	}
}
