Building an Executable .jar file using Netbeans

Question

I've created a java project in Netbeans an am now stuck in the build stage. Everything in my project is set, I have a main class set in its properties and I even set my project as the main project. When I do a "Clean and Build", a dist folder is created with my .jar file. However, the .jar file is not executable, why? I opened the .jar file and looked at the manifest, a main class is specified, so what's the problem? I'm running Netbeans 7.3.1. Thanks.

How are you running it? What error messages are you getting? — MadProgrammer

@MadProgrammer Well when I double click the .jar file, Windows doesn't know what program to use to open it. So it opens up a dialog box for me to pick what program Windows should use. — Navio53

That's not a problem with the Jar, that's a problem with Windows. Try "browsing" to the installation location of your JRE and selecting javaw.exe to open it... — MadProgrammer

The problem isn't with the Jar file but with Windows. You need to register (preferably) javaw.exe as the default application to use when you want to open (double click) a Jar file.

When the dialog popups, browse to the installation location of your JRE and select javaw.exe from the bin folder...
