Hi,
   I'm new to java and i'm learning java. I'm doing programming in
jdbc. I have downloaded mysql-essential-5.0.22-win32.. language &
mysql-connector-java-3.1.13.., & i'm working in jdk1.5.0_06 version.
What i want to do is i should have to access the table which was
already created in mysql. My program is like this.

import java.sql.Connection;
import java.sql.Statement;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;

public class DisplayAuthors
{
    // JDBC driver name and database URL
    static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
    static final String DATABASE_URL = "jdbc:mysql://localhost/books";

    // launch the application
    public static void main( String args[] )
    {
       Connection connection = null; // manages connection
       Statement statement = null; // query statement

       // connect to database books and query database
       try
       {
          Class.forName( JDBC_DRIVER ); // load database driver class

          // establish connection to database

          connection =

             DriverManager.getConnection( DATABASE_URL, "jhtp6",
"jhtp6" );

          // create Statement for querying database
          statement = connection.createStatement();

          // query database
          ResultSet resultSet = statement.executeQuery(
             "SELECT authorID, firstName, lastName FROM authors" );

          // process query results
          ResultSetMetaData metaData = resultSet.getMetaData();
          int numberOfColumns = metaData.getColumnCount();
          System.out.println( "Authors Table of Books Database:" );

          for ( int i = 1; i <= numberOfColumns; i++ )
             System.out.printf( "%-8s\t", metaData.getColumnName( i )
);
          System.out.println();

          while ( resultSet.next() )
          {
             for ( int i = 1; i <= numberOfColumns; i++ )
                System.out.printf( "%-8s\t", resultSet.getObject( i )
);
             System.out.println();
          } // end while
       } // end try
       catch ( SQLException sqlException )
       {
          sqlException.printStackTrace();
          System.exit( 1 );
       } // end catch
       catch ( ClassNotFoundException classNotFound )
       {
          classNotFound.printStackTrace();
          System.exit( 1 );
       } // end catch
       finally // ensure statement and connection are closed properly
       {
          try
          {
             statement.close();
             connection.close();
          } // end try
          catch ( Exception exception )
          {
             exception.printStackTrace();
             System.exit( 1 );
          } // end catch
       } // end finally
    } // end main
} // end class DisplayAuthors
