App won't run outside of the netbeans ide

Question

I created a very simple app using the netbeans ide I made a jframe that when the button is pressed displays text, it works when I select "run file" however when it is built into a .jar it doesn't run, I think it might be because the main is empty and the jframe contains the actual code, I'm lost as I'm a complete noob

Answer 1

it works when I select "run file" however when it is built into a .jar it doesn't run, I think it might be because the main is empty and the jframe contains the actual codeDo this:
In the "projects" tree structure, right click on the current project node which contains the jframe. Select 'Properties' , a dialog would show, select 'Run' in that dialog, you can find a field 'Main class', check whether it shows the correct class, if not click the Browse button in front of it and select the correct class i.e the jframe class.
Now when this is done, right click the Project node again and select 'Build' , then after 'building' right click and select 'Run', if the project runs correctly everything is alright.
Now go to the place where your project is actually saved, go to 'dist' folder and double click the jar file or run the jar through cmd, it would work.... and don't copy the jar file somewhere else, if you want to run it somewhere else, copy the whole 'dist' folder and run the jar from there.... thats what previous reply recommended.
Thanks!
