Is it possible to call Java (GWT) methods from Javascript? It is also unclear from documentation. All samples here http://code.google.com/intl/ru/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html demonstrate calling java functions from JSNI (not JS) functions.

UPDATE 1

Here is a Java code:

public class Test_GoogleWeb_JSNI_02 implements EntryPoint {
/**
 * This is the entry point method.
 */
public void onModuleLoad() {
}

public static void Callee() {
    Window.alert("Callee");
}
}

Here is caller button samples in html:

<input type='button' value='Call' onclick='Test02()'>

And here are some functions I tried and which were not worked:

<script type="text/javascript">

    function Test01() {
        @com.inthemoon.tests.client.Test_GoogleWeb_JSNI_02::Callee()();
    }
    
    function Test02() {
        com.inthemoon.tests.client.Test_GoogleWeb_JSNI_02::Callee()();
    }
    

</script>

UPDATE 2

The following worked.

Java preparation:

public void onModuleLoad() {
    Prepare();
}

public static native void Prepare() /*-{
    $doc.calleeRunner = @com.inthemoon.tests.client.Test_GoogleWeb_JSNI_02::Callee();
}-*/;

public static void Callee() {
    Window.alert("Callee");
}

Caller:

function Test03() {
        document.calleeRunner();
}

Is there a better way?
