[RESOLVED] Persistence Unit

Hi,

I am on my Windows 7 Professional laptop using Netbeans 6.9 to do my Java homework which requires the use of a Persistence Unit. However, the connection to the database isn't recognized and when I go to create "New Data Source" and fill in the appropriate information then press "OK" the new Data Source does not appear in the list. Why is this?

Thanks,
