Problems of connecting mySQL to jboss 4.0.3

Question

hi friends,
I have the problem of bounding jdbc to jboss.
i just want to create a data source for mySQL in JBOSS 4.0.3 application server and i want to access that datasource from my session bean while deploying it, it gives a warning:
09:47:46,046 INFO [EjbModule] Deploying MusicEJB
09:47:46,078 WARN [StatelessSessionContainer] No resource manager found for jdbc/MusicDB
09:47:46,078 INFO [ProxyFactory] Bound EJB Home 'MusicEJB' to jndi 'MusicEJB'
09:47:46,078 INFO [EJBDeployer] Deployed: file:/C:/jboss-4.0.3SP1/server/defaul

09:47:46,187 INFO [EARDeployer] Started J2EE application: file:/C:/jboss-4.0.3S
P1/server/default/deploy/MusicApp.ear
When i open up my jsp page it gives this error:
javax.ejb.EJBException: MusicDAOFactory.getDAO: NamingException for <asg.MusicEJ
B.MusicDAOCloudscape> DAO class :
Cannot connect to database: java:comp/env/jdbc/MusicDB:
jdbc not bound at asg.MusicEJB.MusicBean.ejbCreate(MusicBean.java:56)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
My -ds.xml code shown below:
<local-tx-datasource>
    <jndi-name>MusicDB</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/music</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>chongming</user-name>
    <password>kcm82</password>
<metadata>
         <type-mapping>MS SQLSERVER2000</type-mapping>
      </metadata>
  </local-tx-datasource>My session bean code:
     public MusicDAOCloudscape() throws MusicDAOSysException {
          String dbName = "java:comp/env/jdbc/MusicDB";
                  private DataSource datasource = null;
          try {
               //InitialContext ic = new InitialContext();
               //datasource = (DataSource) ic.lookup(dbName);
                        initialContext = new InitialContext();
                        datasource = (DataSource) initialContext.lookup(dbName);
          } catch (NamingException ex) {
               throw new MusicDAOSysException("Cannot connect to database: " +
                    dbName + ":\n" + ex.getMessage());
          }Please give me advice on this because i have been stuck in this part for 2 wks and i really want to know what going on. If the understand of the codes are not enough, i can post more of the codes if you request.

Connecting to mySQL using JBoss 4.0.3.
1) Download this connector from sql website: http://dev.mysql.com/downloads/connector/j/3.1.html
2) open up and copy mysql-connector-java-bin.jar in C:\jboss\server\default\lib
3) Do not copy the mysql-connector-java-bin-g.jar into the jboss lib folder. Do check it out
4) Next go to your jboss and: C:\jboss\docs\examples\jca and copy the mssql-ds.xml into c:jboss\server\default\deploy
5) Edit the mssql-ds.xml as shown below:
<datasources>
  <local-tx-datasource>
    <jndi-name>MusicDB</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/music</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>chongming</user-name>
    <password>kcm82</password>
        <!-- sql to call when connection is created
        <new-connection-sql>some arbitrary sql</new-connection-sql>
        -->
        <!-- sql to call on an existing pooled connection when it is obtained from pool
        <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
        -->
      <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
      <metadata>
         <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>6) for the context calling do this:
public MusicDAOCloudscape() throws MusicDAOSysException {
          String dbName = "java:MusicDB";
                  //String dbName = "java:/MusicDB";
          try {
               //InitialContext ic = new InitialContext();
               //datasource = (DataSource) ic.lookup(dbName);
                        initialContext = new InitialContext();
                        datasource = (DataSource) initialContext.lookup(dbName);
          } catch (NamingException ex) {
               throw new MusicDAOSysException("Cannot connect to database: " +
                    dbName + ":\n" + ex.getMessage());
     }Notice how i map the jdbc to the jndi name. BTW jboss.xml and jboss-web.xml are not include in my package. The package is still able to run
Thats all folks..
