Good day ,
I tried to run your example provided in step 3 : Embedded Derby and got the
following error :
Exception in thread "main" java.lang.InternalError: One of the management
beans is not compliant.

It seems to be invoked on :
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
How can I fix it ?
thx.
