Java, fatal exception.

Energize · 7 Apr 2008 at 19:50

Everytime I build my project into a jar file with netbeans and try to run it I get a fatal exception error message and the program exits. Does anyone know what can cause this?

Also when I select "run main project" from the run menu, I get the error "java.lang.NoSuchMethodError: main
Exception in thread "main"".

Sounds like a path error, can you go to Start > Run > cmd and then type 'path' (without the quotes) into the command prompt and copy what it says here.

Energize · 7 Apr 2008 at 20:10

C:\Documents and Settings\Ash>path
PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Qu
ickTime Alternative\QTSystem\

You don't have the java bin directory in your path so you will need to add it. In my case it's located at (C:\Program Files\Java\jdk1.6.0_04\bin) but you should browse to "C:\Program Files\Java\" and then look for a folder that has "jdk" in it's name and browse to the bin subdirectory. Once you've found it copy it and type the following into the command prompt, substituting the path to your jdk if different.

path C:\Program Files\Java\jdk1.6.0_04\bin;%PATH%

Make sure you have ;%PATH% on the end or you'll screw up your existing path.

I type that in, but nothing happens.

RobH · 7 Apr 2008 at 21:01

Forgot to mention, type in path again - you should see new stuff in it. Mine is the following:

PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Java\jdk1.6.0_04\bin

Energize · 7 Apr 2008 at 21:02

I did, but it's the same as before. If I do cd c:\ and then type path, it appears there. Still get the exception though.

RobH · 7 Apr 2008 at 21:07

You can add it manually via a dialog:

Press Windows Key + Pause/Break

OR

Right-Click My Computer and select Properties

Once you see the 'System Properties' dialog select the 'Advanced' tab. Next click on the 'Environmental Variables' button.

Select the 'Advanced' tab.

In the bottom section of the window that says 'System Variables' select the entry for 'Path' and click on 'Edit'.

Do as before, add a semicolon to the end of the existing information and then put in the path to the java bin. Press 'ok' on all of the dialogs and try running the jar file again, sometimes a system reboot is required.

Energize · 7 Apr 2008 at 21:15

The path has now been added properly, shows as

"PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\QuickTime Alternative\QTSystem\;C:\Program Files\Java\jdk1.6.0_04\bin".

But I still keep getting the error.

You running Vista by any chance?

Xp pro 32 bit.

Can you execute the jar from the command line?

java -jar <jarfile>.jar

Does it give the same exception as netbeans when you try and run it?

Dfhaii · 8 Apr 2008 at 12:50

All this dicking around with paths :|

Sounds like you're missing your main method (as suggested by the exception, which wouldn't be thrown if there was no java found).

Have you got a public static void main(String[] args) method anywhere? If not you need to add one.

Energize · 8 Apr 2008 at 14:01

Yes I have and I'm able to run the file fine from within netbeans.

This is the main class

Check you are compiling with the correct version of java in netbeans.

Energize · 8 Apr 2008 at 14:48

How?

I only have one version installed though.

Okay. It won't be that then.

I can't check through your code in netbeans as I'm on my mac and don't have the latest version installed. I can check it later for you though on a Windows box.

Does netbeans know where this main class is, it's a property of the project which it'll need to populate the manifest correctly when packaging it up into a jar.

When you run it from netbeans are you running the project or running the file?
