Re: unable to use external javascript in GWT

Thanks Jim and Thomas, $wnd worked for me. But i am facing problem when i changed the location of the go.js , I moved it to the folder where gwt.xml file is present using  <script src="go.js"/> but i am getting the following message. 

14:40:05.077 [ERROR] [opsdashboardlocal] The Cross-Site-Iframe linker does not support <script> tags in the gwt.xml files, but the gwt.xml file (or the gwt.xml files which it includes) contains the following script tags: 

go.js

In order for your application to run correctly, you will need to include these tags in your host page directly. In order to avoid this error, you will need to remove the script tags from the gwt.xml file, or add this property to the gwt.xml file: <set-configuration-property name='xsiframe.failIfScriptTag' value='FALSE'/>

And I am also confused about public folder. Should i create a public folder under my project or under src dir?

Hi ,

I want to use goJS with GWT. I downloaded GOJS javascript and put it in the sampleproject folder under war where sampleproject.nocache.js and sampleproject.devmode.js is present. In sampleproject.html i added 

<script type="text/javascript" language="javascript" src="sampleproject/go.js"></script>

You shouldn't put the file there. The sampleproject/ folder will be cleared by the GWT Compiler.

Either put your script in your "public path" so it gets copied there by the GWT Compiler [1], or put it outside the sampleproject/ folder.

In one of the view i used 

public static native void initGo() /*-{

var $$ = go.GraphObject.make;

}-*/;

when i call this function , exception is thrown:

com.google.gwt.event.shared.UmbrellaException: Exception caught: (ReferenceError) @com.amazon.ops.client.OpsMenuView::initGo()([]): go is not defined.

Can anyone please help me with this?

As Jim already said, you need to use $wnd to escape the sandbox GWT is running in and into the context of the web page, where your script is loaded.
