How to use ApplicationServlet to inject JQuery?

[Mr16 (Mr Decker)]

I’m trying to inject JQuery into a Vaadin app in order tu use it to modify the UI. However, I do not understand how or when to use the ApplicationServlet to inject the JQuery import into the HTML.

I’ve been looking at the following example:

public class MyApplicationServlet extends ApplicationServlet {

@Override
protected void writeAjaxPageHtmlVaadinScripts(Window window,
        String themeName, Application application, BufferedWriter page,
        String appUrl, String themeUri, String appId,
        HttpServletRequest request) throws ServletException, IOException {

    page.write("<script type=\"text/javascript\">\n");
    page.write("//<![CDATA[\n");
    page.write("document.write(\"<script language='javascript' src='./jquery/jquery-1.4.4.min.js'><\\/script>\");\n");
    page.write("//]]>\n</script>\n");

    super.writeAjaxPageHtmlVaadinScripts(window, themeName, application,
        page, appUrl, themeUri, appId, request);
}

}

Should I replace my Application extending class with this one? Or should the Application class call this?

This solution worked for me:

using

as the src-attribute value.
