No icons after exporting [message #1111724]

Hi !
I am facing a problem :
After exporting my project, I don't have any icons on my treeView anymore.

Here is my code :

public class TodoLabelProvider extends LabelProvider {

	private static final Image FOLDER = getImage("folder.png");
	private static final Image FILE = getImage("file.png");


	@Override
	public Image getImage(Object element) {
		if (element instanceof Message) {
			return FOLDER;
		} else if (element instanceof Word) {
			return FILE;
		}
		return null;
	}

	private static Image getImage(String file) {
		Bundle bundle = FrameworkUtil.getBundle(TodoLabelProvider.class);
		URL url = FileLocator.find(bundle, new Path("icons/" + file), null);
		ImageDescriptor image = ImageDescriptor.createFromURL(url);
		return image.createImage();
	} 
}

Here is my build.properties :

output.. = bin/
bin.includes = META-INF/,\
               .,\
               plugin.xml,\
               Application.e4xmi,\
               css/default.css,\
               template/,\
               xslt/,\
               icons/
source.. = src/

I don't understand why it does not work.
Do I have to add something in the plugin.xml ?

Thank you for your help !

ps : it works just fine when i launch the application from eclipse.

Hi,
can you check the deployed version of your bundle, whether the icons are
in it? Do you deploy the bundle as a jar or as a folder?
Regards

I am just exporting my project as an Eclipse product.
So I don't know what to tell you.

Did you ensure to add your icons to the build.properties?

Yes.
My build property is in my first message :

output.. = bin/
bin.includes = META-INF/,\
               .,\
               plugin.xml,\
               Application.e4xmi,\
               css/default.css,\
               template/,\
               xslt/,\
               icons/
source.. = src/

you can see "icons/" in the bin.includes

Oh sorry, missed that.

Did you ensure that all necessary bundles are added to your product?

Open your product configuration and click "Add Required" on the Dependencies tab

In your exported product, there is a folder named plugins. Locate your plugin JAR there and open it with an archive tool. Check if your icons are in there. That's what Jonas was suggesting.

Why doing the loading this hard?

TodoLabelProvider.class.getClassLoader().getResource("icons/"+name) is
much simpler.

Yes, it is simpler.
So I changed my code :

public class TodoLabelProvider extends LabelProvider {

	private static final Image FOLDER = getImage("folder.png");
	private static final Image FILE = getImage("file.png");


	@Override
	public String getText(Object element) {
		if (element instanceof Dico) {
			Dico dico = (Dico) element;
			return dico.getName();
		} else if (element instanceof Message) {
			Message messageJ = (Message) element;
			return messageJ.getName();
		}
		return ((Word) element).getName();
	}

	@Override
	public Image getImage(Object element) {
		if (element instanceof Message) {
			return FOLDER;
		} else if (element instanceof Word) {
			return FILE;
		}
		return null;
	}

	// Helper Method to load the images
	private static Image getImage(String file) {
		URL url = TodoLabelProvider.class.getClassLoader().getResource("icons/"+file);
		
		ImageDescriptor image = ImageDescriptor.createFromURL(url);
		return image.createImage();
		
	} 
}

But it still does not work. Crying or Very Sad

Are you sure that your use cases are the same as when starting the product from within Eclipse? That means, are you sure the objects are of the corresponding type?

Yes, I am.

I am pretty sure that this is :

ImageDescriptor image = ImageDescriptor.createFromURL(url);

which does not work.
Cause i use

TodoLabelProvider.class.getClassLoader().getResource(file)

somewhere else in my code on xml file and it works perfectly fine. I put my icons in the same directory of my xml file but it still does not find them !

Edit :
Ok, I may have find something usefull, I don't know why, but :

URL url = TodoLabelProvider.class.getClassLoader().getResource(file);

clearly does not work. url is null.

Does this have anything to do with the fact that my method is static ?

It shouldn't. Is your code in a plugin or in a fragment?

Ok... I found out...
And I feel really ashamed.

It seems that eclipse is not case sensitive but the exported project is.
My files name extension was in upper case.

I am really sorry I bothered you for this. Thank you really much anyway.

This was the next I was to suggest! This is f** win32 which does not
care about upper/lowercase whereas any sensible filesystem does and jar
is a filesystem type which is one ;-)
