GWT including external javascript file from module's manifest

Question

So I read the documentation about including an external Javascript file directly in the module manifest yourApplication.gwt.xml (http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html)

I have this javascript file called iscroll.js and stored in the war/ folder of the GWT project.

I added the line to the module's manifest of my GWT application:

<script src="iscroll.js"/>

Then from the onModuleLoad() method I call this native JSNI method:

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

Then when I run the code in the browser I keep getting "iScroll is undefined".

Any idea what am I doing wrong?

This is the output of the "iScroll is undefined error"

Answer 1

You need to place the JavaScript file in a public folder, see this stackoverflow answer on how that works: gwt and javascript files and the call to iScroll(.. must be $wnd.iScroll(...
