Hi all

I've a important problem with the type of DataSource I use. If I want to deploy an ear with cmp in JBoss using MySQL I have to write in the deployment descriptor

<datasource-mapping>mySQL</datasource-mapping>

and I don't understand why is necessary to write here what kind of database will be used. In mysql-ds.xml I have already say it with the metadata field.

<datasources>
 <local-tx-datasource>
 <jndi-name>/MyDataSource</jndi-name>
 <connection-url>jdbc:mysql://localhost:3306/jboss</connection-url>
 <driver-class>com.mysql.jdbc.Driver</driver-class>
 <user-name>qqqqq</user-name>
 <password>xxxxx</password>
 <metadata>
 <type-mapping>mySQL</type-mapping>
 </metadata>
 </local-tx-datasource>
</datasources>

Can anyone help me?

I'd want to write only the DataSource jndi-name and JBoss should detect which type of type-mapping must use.

Thanks!
