Newbie Question: Problem with Tomcat and MySql

Hello all,

I am trying to develop a servlet that connects to MySql db.

Here is what I did.
Downloaded mysql-connector-java-5.0.5.

Copied "mysql-connector-java-5.0.5-bin.jar" file under
TOMCAT_DIR//common/lib

As instructed on
http://tomcat.apache.org/tomcat-4.1-doc/printer/jndi-datasource-examples-howto.html

I changed my TOMCAT_DIR/webapps/ROOT/WEB-INF/web.xml file to
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
    <web-app>
  <description>MySQL Test App</description>
  <resource-ref>
   <description>DB Connection</description>
   <res-ref-name>jdbc/TestDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>
 </web-app>

and I added following lines to server.xml under conf.

<Context path="/DBTest" docBase="DBTest"
        debug="5" reloadable="true" crossContext="true">

  <Logger className="org.apache.catalina.logger.FileLogger"
             prefix="localhost_DBTest_log." suffix=".txt"
             timestamp="true"/>

  <Resource name="jdbc/TestDB"
               auth="Container"
               type="javax.sql.DataSource"/>

  <ResourceParams name="jdbc/TestDB">
    <parameter>
      <name>factory</name>
      <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
    </parameter>

    <!-- Maximum number of dB connections in pool. Make sure you
         configure your mysqld max_connections large enough to handle
         all of your db connections. Set to 0 for no limit.

      <value>100</value>

    <!-- Maximum number of idle dB connections to retain in pool.
         Set to 0 for no limit.
         -->
    <parameter>
      <name>maxIdle</name>
      <value>30</value>
    </parameter>

    <!-- Maximum time to wait for a dB connection to become available
         in ms, in this example 10 seconds. An Exception is thrown if
         this timeout is exceeded. Set to -1 to wait indefinitely.
         -->
    <parameter>
      <name>maxWait</name>
      <value>10000</value>
    </parameter>

    <!-- MySQL dB username and password for dB connections -->

     <value>MYUSERNAME</value>
    </parameter>
    <parameter>
     <name>password</name>
     <value>MYPASSWORD</value>
    </parameter>

    <!-- Class name for mm.mysql JDBC driver -->
    <parameter>
       <name>driverClassName</name>
       <value>org.gjt.mm.mysql.Driver</value>
    </parameter>

    <!-- The JDBC connection url for connecting to your MySQL dB.
         The autoReconnect=true argument to the url makes sure that the
         mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
         connection. mysqld by default closes idle connections after 8 hours.
         -->
    <parameter>
      <name>url</name>
      <value>jdbc:mysql://localhost:3306/javatest?autoReconnect=true</value>
    </parameter>
  </ResourceParams>
</Context>

      </Host>

    </Engine>

  </Service>

</Server>

I get following error when I run following code.
Here is error:
SQLException: No suitable driver found for
jdbc:mysql://localhost/javatest?user=tayf&password=nothing SQLState: 08001
VendorError: 0

Here is code

import java.sql.DriverManager;
import java.sql.SQLException;

                                   "user=tayf&password=nothing");

    // Do something with the Connection

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

    out.println("</BODY></HTML>");

  }
}

I would be more than glad if you could help me figure out this problem.
Sincerely yours.
