Java Applet and MySQL
I'm working on a simple inventory program using a Java applet that connects to a MySQL database. Program works fine if I just compile and run it from Netbeans, but it is throwing an exception once I add an applet wrapper.
The java console is only spitting out "createGUI didn't complete successfully" and not the stacktrace or exception message that I need for troubleshooting. What gives?
I've had TONS of trouble getting the html applet tag to work at all. Is this method antiquated?
