So can you please tell me why on earth i get this error and what i should do to fix it?

says it all. Toplink can't find the jdbc driver for the database you're telling it to use.
Supply the driver and you'll get another error (or it might even work if everything else is correct).

thank you. I tought i had the driver, since the connection pool was set properly and mysql jdb driver was placed under glassfish home direcory into a domains folder. Now that i've moved it to the libs folder then it seems to work.

And yes, i fixed my queries as well :) so errors after 15 minutes of code fixing :)
Thanks :)
