GWT ImageBundle问题：图像未显示：包含代码

我在使用ImageBundle时无法显示图像。我遵循GWT教程作为指导，但是我的图像不显示

我可以在我的浏览器中从Eclipse中很好地查看图像-因此它们肯定在那里。使用ImageBundle时，我显然做错了什么，但我无法理解我做错了什么

logo.jpg图像应该只显示自己

gif应该首先显示自己，以覆盖获取facebook用户配置文件数据的RPC，然后将其替换为pic_square url上的图像

当我查看GWT生成的html时，我发现logo.jpg图像应该在哪里，有一个gif图像[但我不明白这是从哪里来的]

任何帮助将不胜感激-源代码如下

我不明白为什么，但这现在起作用了，我没有做任何更改。

在您编译项目并将生成的war放入服务器公用文件夹之前，图像不会显示。您只是请求了一个不存在的文件
