inputmask in combination with gwt in the following way:


public class JQueryMask {

    public native static void setMask(Element elem,String mask) /*-{

        $wnd.jQuery(elem).find("input").inputmask(mask);
        $wnd.jQuery(elem).find("input").change(function(e) {

            });
    }-*/;

    public native static void removeMask(Element elem) /*-{
        $wnd.jQuery(elem).find("input").inputmask("remove");

    }-*/;


    public native static void setMaskWithGreadyFalse(Element elem,String mask) /*-{

    $wnd.jQuery(elem).find("input").inputmask({mask:mask,greedy:false});
    $wnd.jQuery(elem).find("input").change(function(e) {

            });

    }-*/;

}

This methods are called when the widget is initialized and everything works in the browser. The jQuery variable does not get initialized this produces the same exception:


console.log($wnd.jQuery());

also:

console.log($wnd.$());

Which is:


com.google.gwt.core.client.JavaScriptException: (null) @assembly.gwtlib.gui.plugins.JQueryMask::removeMask(Lcom/google/gwt/dom/client/Element;)([JavaScript object(77)]): null

GWTTestCases use their own HTML host page (because, well, technically, you may not even have one, or not a static one), so if you need jQuery for your tests, you have to load it from the tests themselves (e.g. using ScriptInjector, either from your test method or from gwtSetUp())

Thanks to Thomas Broyer I have implemented the following code: 

 Callback c=new Callback() {

        @Override
        public void onSuccess(Void result) {
             ScriptInjector.fromUrl("urlTo/jquery.inputmask.js").setWindow(ScriptInjector.TOP_WINDOW).setCallback(new Callback<Void, Exception>() {

                @Override
                public void onSuccess(Void result) {


                    //Your tests
                }

                @Override
                public void onFailure(Exception reason) {
                    reason.printStackTrace();
                    junit.framework.Assert.fail(reason.getMessage());


                }
            }).inject();

        }

        @Override
        public void onFailure(Exception reason) {
            reason.printStackTrace();
            junit.framework.Assert.fail(reason.getMessage());

        }
    };
    ScriptInjector.fromUrl("urlTo/jQuery-2.1.4.min.js").setWindow(ScriptInjector.TOP_WINDOW).setCallback(c).inject();//setWindow(ScriptInjector.TOP_WINDOW) is important
