Under JBoss 4.0, deploying the bundled hsqldb-ds.xml
automatically creates an MBean with the following
ObjectName:

Code:

jboss.jdbc: service=metadata, datasource=DefaultDS

But other ds-xml files, including Firebird and MySQL,
do not create a similarly named MBean. Evidentally,
this MBean is required by the CMP deployer, because
when I try to deploy my Firebird CMP .jar I get:

Code:

org.jboss.deployment.DeploymentException:
Failed to obtain type-mapping metadata from the
metadata library MBean:
jboss.jdbc:service=metadata,datasource=BigDealDS is
not registered.;

• nested throwable:
  (javax.management.InstanceNotFoundException:
  jboss.jdbc:service=metadata,datasource=BigDealDS is not
  registered.)
