GWT包括来自模块清单的外部javascript文件

Question

所以我阅读了有关直接在模块清单yourApplication.gwt.xml中包含外部Javascript文件的文档(http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html)

我有这个名为iscroll.js的javascript文件,存储在GWT项目的war /文件夹中.

我将该行添加到我的GWT应用程序的模块清单中:

<script src="iscroll.js"/>

然后从onModuleLoad()方法我调用这个本机JSNI方法:

private native void initJavascript() /*-{
  $wnd.myScroll = new iScroll('jokeWrapperLabel');
}-*/;

然后,当我在浏览器中运行代码时,我不断得到"iScroll未定义".

知道我做错了什么吗？

这是"iScroll未定义错误"的输出
