Vaadin不允许导入外部脚本

Question

im using Vaadin and trying to import jQuery and my own script. I have extended ApplicationServlet class and redefined this method

@Override
protected void writeAjaxPageHtmlHeader(BufferedWriter page, String title,
        String themeUri, HttpServletRequest request) {

    try {
        super.writeAjaxPageHtmlHeader(page, title, themeUri, request);
        page.write("\n<script type=\"text/javascript\" src=\"/VAADIN/themes/MyTheme/js/jquery-1.7.1.js\"></script>");
        page.write("\n<script type=\"text/javascript\" src=\"/VAADIN/themes/MyTheme/js/script.js\"></script>");
        System.out.println("Added jQuery and other scripts to page header.");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

and changed in web.xml servlet class to my own, but when i get it running my scripts don't work, so i open JavaScript Console and get this two messages:

Not allowed to load local resource: file:///VAADIN/themes/MyTheme/js/jquery-1.7.1.js

Not allowed to load local resource: file:///VAADIN/themes/MyTheme/js/script.js

Why is this happening, what can i do?

themeUri参数提供了正在使用的主题的URI，因此请尝试在src属性中使用它：

page.write("\n<script type=\"text/javascript\" src=\"" + themeUri + "/js/jquery-1.7.1.js\"></script>");
