In 0.9.2 and before, the JDO database was using the private JNDI namespace of the very first CMP accessed to grab a datasource and hold onto it for use on all requests into the CMP container. This was configured with something like this:

   <database name="Global_TX_Database" engine="instantdb">
       <jndi name="java:comp/env/jdbc/basic/entityDatabase" />
       <mapping href="conf/default.cmp_mapping.xml" />
   </database>

This was just wrong. We've switched it so that the "jndi" tag of a Castor database.xml file can be set directly to the global JNDI name of a Connector element declared in an openejb.conf file.

   <database name="Global_TX_Database" engine="instantdb">
       <jndi name="java:openejb/connector/Default JDBC Database" />
       <mapping href="conf/default.cmp_mapping.xml" />
   </database>
