How to create a executable jar with a particular class in a project in netbeans

Question

This is my first question on stack overflow. Please have a look at this first, please!!

I am creating an executable jar file by clicking on the button surrounded with grey color. The problem is that the exxcution of the application always starts from the "PersonalAssistant.java". I want my application to begin its execution from "App.java" which also contains a main() method.

So, basically the jar file which I want should begin its execution from App.java class which has a main method.

I don't know how to change the path or execution class for jar. Please help me!!!! I'm stuck with this silly problem. But I want a solution for this.

I'm using Windows10 with Netbeans 8.2 IDE

Answer 1

You should be able to reconfigure your IDE and rebuild the executable jar specifying which class you want to use as the executable.

in your IDE add java -cp myjar.jar App to your compile command

Look at the picture above. Right-click on your project and select Properties . Select Run . Look for the Application Class field. In my example, I have javafxapplication211.Main . This structure is projectName.MainClass . You should just need to change the MainClass part to the class you want to start your project. For example, if Main.java was starting my app and I wanted to change it to App.java . I would change javafxapplication211.Main to javafxapplication211.App .

If you hit Browse , it will give you a list of available classes that can start the application.
