invient chart add on-vaadin indication in web.xml - charts

Question

I have learnt from other posts that the mainServlet file has to be modified according to the Demo code. N then servlet file had to be indicated in web.xml
However, in my web.xml, I already had a servlet class indicated in order to use my Rest service.
Question: How can I solve this?
Following is what I am doing:
1:
<servlet>
<servlet-name>ServletAdapter</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ServletAdapter</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
Problem is that Invient Widgetset won't be loaded.
2: and if I had to indicate the servletfile here, then how I am supposed to let my Rest Service works? My Rest service is used to for secure login with auth-constrain.
<servlet>
<servlet-name>VaadinApplication</servlet-name>
<servlet-class>suricate.vaadin.MyApplicationServlet</servlet-class>
<init-param>
<param-name>application</param-name>
<param-value>suricate.vaadin.MyApplication</param-value>
</init-param>
<init-param>
<param-name>widgetset</param-name>
<param-value>com.example.myapp.widgetset.MyAppWidgetSet</param-value>
</init-param>
</servlet>
I hope someone could help me out of this. Thanks very much in advance.

You could override the writeAjaxPageHtmlVaadinScripts method in the ApplicationServlet class and inject the required invient chart js and css files.
Here is what I have done.
public class TogetherApplicationServlet 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\" language=\"javascript\" src=\""
+ appUrl
+ "/modules/core/jquery/jquery-1.4.4.min.js\"></script>\n");
page.write("<script type=\"text/javascript\" language=\"javascript\" src=\""
+ appUrl + "/modules/core/js/highcharts.js\"></script>\n");
page.write("<script type=\"text/javascript\" language=\"javascript\" src=\""
+ appUrl
+ "/modules/core/js/modules/exporting.js\"></script>\n");
super.writeAjaxPageHtmlVaadinScripts(window, themeName, application,
page, appUrl, themeUri, appId, request);
}
}
You will have to modify your suricate.vaadin.MyApplicationServlet like I have done above. Make sure to include the correct path to the invient chart js and css files.
