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.
