GWT 2 CssResource error

[shahid]

I have a GWT 1.7 application and I want to upgrade it to GWT 2
Milestone 2. The application uses 2 big external CSS files. In GWT 1.7
I had a public folder and put both the CSS files in the folder and my
application compiled and worked fine. Now for GWT 2 I have created a
ResourceBundle class and put all image sprites and CSS as follows:

public interface ResourceBundle extends ClientBundle {

public static final ResourceBundle INSTANCE = GWT.create
(ResourceBundle.class);

@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();

@Source("com/web/tech/public/stylesheet2.css")
public Css stylesheet2();

@Source("com/docobo/keswick/keswickweb/public/images/
organisnew.gif")
public ImageResource add_org();

.....
}

The Css class is an empty class extending CssResource :


public interface Css extends CssResource{

}


Then in my onModuleLoad() I use :


StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet1().getText
());
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet2().getText
());

When I compile I get the following error:


Rebinding
com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle
Invoking <generate-with
class='com.google.gwt.resources.rebind.context.InlineClientBundleGenerator'/
>
Creating assignment for gxt_gray()
Replacing CSS class names
[ERROR] The following unobfuscated classes
were present in a strict CssResource:
[ERROR] x-tab-scroller-left
[ERROR] x-tab-strip-disabled
[ERROR] ......loads of other styles

Fix by adding String accessor method(s) to the CssResource
interface for obfuscated classes, or using an @external declaration
for unobfuscated classes.

Following the above instruction when I use @external above all my
style classes inside the CSS file I get the following error :

It's not to be used "above", as a Java5 annotation; see

Thank you Thomas. Putting @external next (left) to the style solved
the problem :) regards shahid

My css background images are not working though. May be there is a
different way to use background images in GWT 2.
