Dumb question but...
I am new to orion and j2ee and don't understand how the container
managed persistence maintains the sql used to update a database. I know
I have to map the ejb member variables to the databas efields in the xml
using the <cmp-field><field-name> descriptors, but how does this map to
SQL?
thanks for any help/advice.
