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.

 

[1] see http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html

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.
