Beginner Has Problem With Loading JDBC Driver Using MySQL

Question

Hi, I am having problem with loading JDBC driver, and need your diagnotic help.
1. I have installed MySQL (C:\mysql), created a databse (soup), and created a littel table (VIDEOS). I am able to see the table in the console:
sql> select * from videos
2. I have downloaded the latest version of Connector/J (mysql-connector-java-3.1.0-alpha.zip), and unzip the zip file into my C:\ directory.
3. I copied the mysql-connector-java-3.1.0-alpha-bin.jar to the C:\j2sdk1.4.1_02\jre\lib\ext folder and it is in my CLASSPATH
4. MySQL server is running
C:\> C:\mysql\bin\mysqld-nt --standalone
5. open another DOS window and use the database
mysql>USE SOUP
6. succesfully compiled a Java program (javac Test.java):
import java.sql.* ;
public class Test
public static void main( String[] args )
try
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
try
Connection con = DriverManager.getConnection( "jdbc:mysql://localhost:3306/soup" );
try
Statement statement = con.createStatement();
ResultSet rs = statement.executeQuery("SELECT TITLE FROM VIDEOS");
while ( rs.next() )
System.out.println( rs.getString( "TITLE" ) );
rs.close();
statement.close();
catch ( SQLException e )
System.out.println( "JDBC error: " + e );
finally
con.close();
catch( SQLException e )
System.out.println( "could not get JDBC connection: " + e );
catch( Exception e )
System.out.println( "could not load JDBC driver: " + e );
7. when I run the Java program (java Test), I got
the message:
could not load JDBC driver: java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
What am I missing?

Hi,
I missed to specify test in my last post.
Try running your program by explicitly setting the classspath when
running your program . java -classpath c:\mysql-connector-java-3.1.0-alpha-bin.jar test
Make sure your jar file contains org.gjt.mm.mysql.Driver class
