HI Omidh,

Thanks for help. I used <h:outputText> to trigger the code to add javascript. If the method returns "work done", it would show up on page. Dave

    Try to return a String...

    public String getAddResource() {
    FacesContext context = FacesContext.getCurrentInstance();
    AddResource addResource = AddResourceFactory.getInstance(context);
    addResource.addInlineScriptAtPosition(context, AddResource.BODY_END,
    script1);
    addResource.addInlineScriptAtPosition(context,
    AddResource.BODY_ONLOAD ,
    script2);
    return "work done";
    }

    I added these in my Portlet-Impl in the render() and it works so
    far ok
    (without problems):

    FacesContext fCtx = null;
    fCtx = facesContext(request, response);

    AddResource resource = AddResourceFactory.getInstance(fCtx);
    logger.debug("resource: "+ resource);

    resource.addJavaScriptAtPosition(fCtx, AddResource.HEADER_BEGIN,
    "/tiny_mce/tiny_mce.js");

    resource.addInlineScriptAtPosition(fCtx, AddResource.HEADER_BEGIN,
    "tinyMCE.init({" +
    "mode : \"textareas\", " +
    "theme : \"advanced\", " +
    "});");
