Hi Marius, Since the first approach which is "1) edit the wysiwyg_createEditor velocity macro from macros.vm" is simpler, I will modify macros.vm. You said "new WysiwygEditor($jsVarName); with something like window["${fieldId}_editor"] = new WysiwygEditor($jsVarName);" Could you please explain briefly what does "window["${fieldId}_editor"]" mean? What is it for? Is it a function of javascript? In the macros.vm I found "Wysiwyg.onModuleLoad(function() {new WysiwygEditor($jsVarName); $jsVarName = undefined;});", I did not find any "window" stuff.

"window" is a predefined JavaScript object. See http://w3schools.com/jsref/obj_window.asp . It has global scope so you can access its properties everywhere. My suggestion was to save a reference to the editor instance on the window object so that you can access the editor later.

So after the first step, I got the reference, is the reference stored in window["${fieldId}_editor"] variable?

You should be able access the editor using window['content_editor'] in JavaScript.

Since don't depend at all on WYSIWYG Java code is not possible and do not bring you more work, I think should go with "i) access the editor in Java (GWT) code by writing a simple native getter". For the code you provided "editorJSReference.@com.xpn.xwiki.wysiwyg.client.editor.WysiwygEditorApi::editor;" I never saw code like this, is the @ for Java annotation or Component? Is there any document I can read to learn about the related rationale/knowledge? 'cause I have no clue what it means. So this line will return the WYSIWYG editor's reference restored/declared in the macros.vm file?

That is GWT's JavaScript Native Interface (JSNI) notation. See http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part... . Replace editorJSReference with window['content_editor'].

I tried to add a new page in the draft document for Loading GWT in Xwiki page, It seems I can't add new page, only editing existing document. Should I add something behind your "Writing GWT applications in XWiki", so you could create a new one or something else. If there are work I can do to save your time or to make Xwiki better, feel free to assign me the work. I am more than happy to help.

I created http://dev.xwiki.org/xwiki/bin/view/Drafts/LoadingGWTApplicationsInXWiki for you. Hope this helps, Marius

Thank you for taking your time to help me!
