I just double checked. My cayenne.xml contains:
<node name="mysql"
datasource="mysql.driver.xml"
adapter="org.objectstyle.cayenne.dba.mysql.MySQLAdapter"
factory="org.objectstyle.cayenne.conf.DriverDataSourceFactory">
<map-ref name="mysql"/>
</node>
Versions:
Cayenne Release Notes 1.2 B3 (beta)
mysql Ver 14.7 Distrib 4.1.14, for redhat-linux-gnu (i386) using
readline 4.3
I did some more work, but couldn't get any further,
