From memory, File > Export... > Java > As JAR

You get only the jar this way. For a more complete export, I think you need to the Processing plugin.

what do you mean from memory? I can't find that.

haha
sorry :) where?
I can't find Memory...

Jesse is right, I mention the feature from my memory, no relation with a computer's memory!
There is an Export menu item in the first entry of the menu bar.

If you are looking to export from Eclipse to any form of output, then the jar file would be your best option.

For some school related projects before, I was looking to export it to an exe file just to be able to run it on windows, though you can only do it using a third party program that would compile the program down to platform specific machine code.

That kind of defeats the purpose though as that would become platform independent.

Still working at it... :)
when to use 'jar file' and when 'Runnable JAR file' since the first one also want's to start with jar launcher.

Also i get a error when i try to run my exported file and it tell's me to check to console, what console?
:(

How do you run the exported file?
If you do it from the command line, the error should be there.
If you do it from a Web browser, you have to activate the Java console, which can be specific to your browser.
You can also activate it in the Java Control Panel, "Advanced" tab.

i double click it :)

this is the error

i don't have a class heermoes, so that makes sence, but i don't want a class heermoes!

A jar is runnable because inside it, you have a META-INF folder holding a MANIFEST.MF file (there can be other files, particularly if you sign the jar).
Inside this text file, you have, among others, a line, like: Main-Class: conexus.util.JarInventory (example from a random jar I took). I suppose you have similar line there, with heermoes.jar there.
Perhaps you should double-check the settings you have in the jar export wizard of Eclipse.

How do you open it? I mean not to run it but to see that folder.

Also,

Caused by: java.lang.ClassNotFoundException: heermoes.jar

If i rename the filename then that will be the new error.

I also saved the Manifest file when exporting, there it is correct:

Manifest-Version: 1.0
Main-Class: AV_heermoes

Also if i use the option to use a exported manifest file it goes still wrong.

I tried multiple things, but maybe someone sees something that is seriously wrong.

You open a .jar file with an archiver, like a .zip file. 7-Zip works fine for this.

" Caused by: java.lang.ClassNotFoundException: heermoes.jar"
The message is strange, actually. With ClassNotFoundException, we usually have a class name, not a jar name. Are you sure your Java runner (file association) is correctly configured?

Or maybe you try to run an applet jar without a main() method that would allow to run it from the command line.
