Netbeans Issue

[Swick]

I have a problem when I create a java application, for some reason no main class is created, I can follow the HelloWorld tutorial word for word but I still have the same problem. When I first installed NetBeans everything was fine, then the next day this problem appeared out of no where.

What should happen: (from "Hello World!" for the NetBeans IDE (The Java™ Tutorials > Getting Started > The "Hello World!" Application))


What I get:


I hope there's an easy solution because I'm eager to start learning, this is holding me back. Thanks.

Have you tried looking in the NetBeans help to see whether there's anything about creating/setting the main class? You're going to need more knowledge on that as you continue to use NetBeans, so a simple answer to the immediate problem wouldn't really help you.

this is holding me back

Be curious. Click around. Right-click around. Go through all the sections and tabs in properties dialogs. Look up the Help for anything you don't understand.

I've looked everywhere for a solution, asked on the netbeans forum but no one replied (thanks for replying by the way).
I can't right click and add a java class, the java folder isn't even there like I'm sure it was before, just java FX and the rest.

I can't find anything online about this problem so I'm pretty stuck.

Once you create that package is it exist physically in the project folder? Check it with and without closing the IDE.

What java folder? Could you be more specific?

When you add a new item to the project there's categories such as java, java FX etc. But it should make the main class automatically.

No it isn't.

No it isn't.

You mean that any of the created packages are not exist once you reopen the NetBeans?

[DarrylBurke]

Um, the <default> package is represented by the /src folder. I don't see any named packages in the screenshot.

Well I can't find that default package anywhere. The package isn't named correctly when the project is made.

When you created the project did you ensure the 'Create Main Class' check box was ticked?
I would check myself but I don't have Netbeans here.

Yes, I've tried it several times. Like I said, it worked fine at first (the day before I came across this problem) so I know for sure that I'm not doing anything wrong.

What version of Netbeans is it, on which OS?
Any idea if there's been an auto-update to it that might have broken it?

The latest version (7.1) on Windows Vista 32bit, pretty sure there wasn't an auto update. :|

I don't know what the big deal is. Even if your project templates have somehow got corrupted and you can't automatically create the main class along with the project, what stops you from creating a class and identifying it as the main class?

If you can't discover from the help file how to do that, then you need a tutor. Anonymous, time-delayed help on a forum just won't cut it.

I am not talking about the default package. What I am asking is once I you create a package you can see a folder with the same name in /src.
