Jar doesn't work

[mad72584]

Good morning.

I have a problem with the construction of a Jar of a program I have. I make it with "Clean and build Main Project" in netbeans 7.0, then it creates the "dist" folder and into a jar and a readme. The jar does nothing, the cursor becomes a moment to fleach with the clock, but ends up doing nothing. What can happen?


Thank you very much.

I guess your program only uses console as input/output?
Try to run the jar from a batch file:

java -jar MyJarFile
pause

Console application or GUI?

db

[mad72584]

GUI with swing. I'm sorry

[Norm]

Try to execute it in a command prompt window:
java -jar <YOURJARFILENAME>.jar
Copy the console window here.
To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

Is that where your jar file is located?
You need to do that command in the directory containing your jar file.

[Norm]

Use the dir command to display the contents of the directory you are in to make sure the jar is there

This is the correct lines:

So now you've got a different problem entirely, a NPE. Time to do some debugging. First find out where the error is (line 63 in esta.Interfaz, next find out what objects you're trying to dereference on that line.

[mad72584]

my line 63 is: botonCerrar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Cerrar.png")));
that initializes a JButton

and

the line 8 is:

1 
2  package esta;
3
4  public class Esta
5     {
6    public static void main(String[] args) 
7         {
8         Interfaz inter = new Interfaz();
9         inter.Comienza();
10        }
11   }

in "Interfaz" I make all the graphic part whit other classes.

When I clic on "Clean and build Project", on the output window appears this:

mmmm caramba! I find that the error in this line:

botonCerrar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Guardar.png")));

is anything about the image I use to put to that JButton. I put the same image forn the otre JButton I use in this code, and the JAR runs! but the image I need add to this button does not!

[Norm]

I put the same image forn the otre JButton I use in this code, and the JAR runs!

That would mean that your code is good, now you must Make sure the image exists in the folder and that you have spelled its name correctly.

[mad72584]

But the code works when I run it from netbeans, the icon apears, but in the jar does not. The image exists and the name in the code is correctly.

[Fubarable]

The image exists....

But is the image in the Jar file and in the correct location relative to the class files?

Also, please watch your language. I have edited a post above to remove some foul language.

[mad72584]

I'm so sorry couse my word, I did no mean bad words, only it was a expression but I know I don't have to use it.

these are the lines:

59        botonGuardar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Guardar.png")));
60        botonGuardar.setEnabled(false);
61        botonImprimir = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Imprimir.png")));
62        botonImprimir.setEnabled(false);
63        botonCerrar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Cerrar.png")));
64        botonCerrar.setEnabled(false);
65        botonAyuda = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Ayuda.png")));

the line 63 is which has problem, and the file "Cerrar.png" exists whit the identical characteristics than other images.

When I change the line 63:

63        botonCerrar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Cerrar.png")));

for this one:

botonCerrar = new JButton(new ImageIcon(getClass().getResource("/Imágenes/Guardar.png")));

the jar works and ofcourse with tow buttons with the same icon.

[Fubarable]

Is the Cerrar.png image present in the Jar file in the /Imagenes/ directory? The Guardar.png is certainly there, but I have to wonder about the "close" image.

[mad72584]

The image exists the same way than the other files (images): the same location, the same kind file, the only defference is the name.

And can you explain this part?:

The Guardar.png is certainly there, but I have to wonder about the "close" image.

I don't understand what you mean. Excuse me.

[Fubarable]

What I mean is, have you inspected the jar file to see that the close/cerrar image is in fact present, that it is not corrupted.
