NetBeans 6.9.1 Java Application won't compile/run

Question

I just downloaded the latest version of Netbeans - 6.9.1. I've been using 6.8 for some time for my PHP and HTML development on websites and whatnot. My business partner needs a cross-platform desktop application developed and so I figured that Java would be the way to go.

Here's my problem - I downloaded the 6.9.1 version of NetBeans with all languages included, as well as the latest Java Development Kit (64bit). After installing those I started up a brand-spankin'-new Java desktop application project in Netbeans. After looking at it and getting used to the GUI I hit the compile/run button (keep in mind that I did not change ANY code at all, this is just the default bit of code that Netbeans produces when you create the Java Desktop App project); it then said it compiled, but with errors and asked if I wanted to run it anyway. I clicked 'Yes', but nothing happens.

What's the deal? Why won't the application compile properly? I've not edited ANYTHING in the code or GUI at all, so I can't imagine what the problem is.

The error message (NetBeans Output) is as follows:

So, what's the dealio? A problem with the JDK? Something messed up with my NetBeans install? Some other SDK/Library/Framework I need to install? I've positively NO clue why the default project code doesn't work.

Answer 1

Looks like byte code has been generated to say that the source could not compile.

Fix the basic errors first.

Answer 2

Nevermind, apparently I did accidentally modify the code or whatnot. I created a new Java Desktop App project with NetBeans, hit the compile/run button, and it ran just fine.

My apologies.
