I am about to start some testing with JBOSS 4.0.5 and MySQL Cluster.

I have a traditional mysql-ds.xml to connect to a single instance :

 <local-tx-datasource>
    <jndi-name>mysql-propcoent-bandr</jndi-name>
    <connection-url>jdbc:mysql://172.16.82.1:3306/mytestdb</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>jboss</user-name>
    *****
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <!-- 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) --><min-pool-size>10</min-pool-size>
    <max-pool-size>35</max-pool-size><transaction-isolation>TRANSACTION_READ_UNCOMMITTED</transaction-isolation>
       <type-mapping>mySQL</type-mapping>
    
 </local-tx-datasource>



Does anybody know or can tell me how to connect it to a mysql cluster?

Cluster config is as below:

Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2    @172.16.82.129  (Version: 5.0.51, Nodegroup: 0)
id=3    @172.16.82.130  (Version: 5.0.51, Nodegroup: 0, Master)

[ndb_mgmd(MGM)] 1 node(s)
id=1    @172.16.82.1  (Version: 5.0.51)

[mysqld(API)]   2 node(s)
id=4    @172.16.82.129  (Version: 5.0.51)
id=5    @172.16.82.131  (Version: 5.0.51)



Any help appreciated Thanks.
