"An error has occurred.
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. 
Target exception message: Class name is wrong or classpath is not set 
for : org.apache.derby.jdbc.EmbeddedXADataSource"

Please note that the error is similar when I specify the non-xa 
datasource (...embeddedDatasource).
Also very importantly the derby.jar is not only copied to the lib dir of 
the domain, the classpath settings in the 'Application Server --> jvm 
settings -->classpath prefix is also set to point to derby.jar. (And 
yes, the server has been restarted numerous times.)

> What's in the server.log?

Sorry for the lengthy log, but ALL of the following was generated by the 
one ping request: (Again, please excuse.)
