Vaadin call aplication with input parameter

i am working with Vaadin 7.6.6

My Dashboard  is colling from  an HTML  page.
servelet I was  implemented  ,  doesn't  get  input parameter  . Implementation form my  servic in servelet is this :

protected void service(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {
   super.service(request, response);
   username= request.getParameter("un");
   password= request.getParameter("pw");
}

I don't know way  I cannot  get  outher  aplication's  parameters when first time  click on  it from  server where is  first sistem HTML page.

Please try to follow this tutorial: https://vaadin.com/docs/-/part/framework/advanced/advanced-embedding.html. Then, just add the parameters as query parameters to the browserDetailsUrl and/or the serviceUrl, for example: "serviceUrl": "myui/?un=anna&pw=annapassword". That should make those parameters available in your service() method.

Hi 

On   server   I have  tomcat  7.0.52.0 but on my machine it is    7.0.65  . I dont know is it problem
but when I   deaploying  my app on  server  , first  start to execute  custom UIProvider  code after that  service() in custom  servlet. On my machine  it is  reverse , first  execute  service() , after that  UIProvider code. 

have you any idea ?

thanks

Hi

My problem  are  manifested on  one more way.
If I  deaploying   app  on  tomcet 7 on Linox  and start  aplication  servletInitialized() method  is not  called .
another, if I  deploy aplication on my local machine  where tomcat  is  7.0.65     servletInitialized()  method  is execut in any way.
I am confused  with it .
thanks 

There is definitely something very weird going on in your setup. Servlet specification mandates that servletInitialized() method MUST be run prior the webapp is put to the service.

I start server's applicetion  by sending post call  .
has it something to do ?

thanks
