i am duly embarrassed

org.apache.derby.jdbc.EmbeddedDriver is in derby.jar

i am using persistence.xml, which has url/usr/pwd

i place derby.jar into JRE's lib/ext (as i was originally told to do) and
appclient works GREAT - no error.

i was definitely in the Twilight Zone - sorry.

Ray,

Can you send us a stack trace (with all nested parts available in the log)?

But this statement surprises me: "driver is in toplink-essentials.jar" -
there is no database driver in that jar.

Also, do you look up a database by jndi name, or provide url/usr/pwd as
toplink... properties?

thanks,
-marina
