You can call servlet from FacesContext. In order to pass parameters to servlet you can use query params. Sample code for that will be as follows.

The problem that I have a navigation , so when I did this approach I got the following exception
javax.servlet.ServletException: Cannot forward after response has been committed

so how can I provide a navigation role which is important to display the user message that the user's parameters were submitted .
and in the same time I can call the servlet ??

I tried to provide that by the servlet it self , but the response format of the servlet as xml and it must be that because the system logic requires that.

any help ??

Please don't ask the same question twice.

Customer surveys are for companies who didn't pay proper attention to begin with.
It is sorta covered in the JavaRanch Style Guide.
