How to generate jar using NetBeans

I am using NetBeans 6.1 to develop my software on a Vista based machine. My application is currently made up of two classes that live as two separate source files. When I click on the Run Main Project button on the IDE everything works fine. If I click on the Build Main Project button and the double click on the generated .jar file that sits in the dist folder I get a �Could not find the main class. Program will exit.� Message. How should I generate the jar file so it will run?


Thanks,

Enrique

It's because there's no Main-Class field in your MANIFEST.MF. In order for NetBeans to add the Main-Class field in the MANIFEST.MF, you need to set the main class in your NetBeans project.
1. Right click on the project->Properties->Run
2. Set the main class.

Hope this helps.
