I am using NetBeans and I have the MySQL server with SQL db running on my computer. I have a desktop app with embedded db. I would like to find some good info on how to add button functionality to initiate another desktop app.
I would like to explore possibilities to initiate the MySQL command window. Is there a good way to add functionality of these applications so to have them available on my main desktop?
My interest concern importing the eclipse file that could start the???.jar when the button actions fired. so I would need Java code that I could put in this class.
