Hi;
Although I have no problems connecting to my new Derby, via jdbc, I 
cannot get a 'ping' when setting up a j2ee pool and jndi connector in 
the Sun app server. I followed the instructions on the java.net 
blog,for embedded, the classpath is set, have tried various javax 
connectors, the xa version and non xa version, to no avail.
Your help will be appreciated.
Thanks

Nat,
What's the error you see?
"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.)

Does a derby.log get created? If so, is it where you expect it to be?
Yes. Yes. (in the "derby.system.home" directory.)
