Help with using a jbutton actionlistener to open a text file
I've been building a contact editor GUI using Netbeans 7, and I'm stuck on how to open a text file with a button. I've searched around, but only found advice relating to jfilechooser. The text file contains all the entries submitted to the contact editor, and I don't need it to be opened within the GUI, just with notepad outside of the program.
Any help is appreciated!

with notepad outside of the program.
If you want to specify which program to use, see the Process and Runtime classes where you can specify the full ccommand line to be executed.

Why do you need to open the file in Notepad? Why can't you display the file on a JTextArea or a JEditorPane?
If you are determined to use Notepad then you can investigate Runtime.exec but make sure you google "pitfalls of runtime exec" or something similar.
