Re: How get the MySQL data in a Netbeans UI

Hello Phil,
Your answer is clear, but I don't understand how to do it in my program. I
tried to change the status of the methods in several ways, but keep having
this problem or don't get any output at all.
I found another example that does work inside Netbeans but not from the
command line.
But from Wade I understand this is the wrong list for my questions so I will
ask somewhere else.
