Yes you can access I got it working
kind of many steps involved
Im not putting the exact "name=values" since I dont have access right now
Here it is in Short:
JDBC provider select other for the driver,
provide the class path mysql..bin.jar,
for the connection use MysqlConnectionPool....
create Data Source,
provide the mysql user password
link the Jauth to the data source Component managed auth.
in custom properties
Hope this helps,
If you still have problem let me know I will type it in detail
latter this evening.
