I got a "fail to obtain type-mapping metadata" error when deploying CMP. I am using JBoss 4.0.0./Java 1.4. I am using mySQL database.

My mysqldb-ds.xml in my deploy directiory looks like:


<local-tx-datasource>
<jndi-name>DefaultDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/test</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>

</local-tx-datasource>



I have the datasource in standardjbosscmp-jdbc.xml to have the value "java:/DefaultDS". The datasource and type-mapping in standardjaws.xml have the values "java:/DefaultDS" and "mySQL", respectively.


I also have the datasource and type-mapping in my own jbosscmp-jdbc.xml in META-INF to have the values "DefaultDS" and "mySQL".

Do you know why is it complaining jboss.jdbc:datasource=DefaultDS, service=metadata is not registered?

Thanks
