Question

I have created a ClientBundle as below.

public interface DataResources extends ClientBundle {
    DataResources IMPL = (DataResources) GWT.create(DataResources.class);
            @Source("marker.png")
            ImageResource markerimage();

            @Source("settings.png")
            ImageResource settingsimage();

            @Source("back.png")
            ImageResource backimage();
}

I am getting an error that it cannot find the resources. I have all the images in the top level of my “war” directory.

00:00:04.302  [ERROR] Resource marker.png not found. Is the name specified as Class.getResource() would expect?

Answer 1

Data resources are referenced relative to the package (folder) your class is in. You can try moving the images in the same package to check if that works.

I would typically have my resource interface in a package – something like com.project.resources. The images would then be in com.project.resources.images, and the Source annotations would take the form @Source("/images/marker.png").

By following this package structure you can also bundle your resources/images in JARs and can include and reference them in other projects.
