I don't understand why you expect this to work. Adding FormParam causes the JAX-RS runtime to consume the input stream, so when you try read the form-based property from the HttpServletRequest it would obviously return null or empty value.
If you prefer to read form-based properties as HttpServletRequest parameters then avoid using FormParam

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 3.1.7
>            Reporter: Neal Hu
>            Assignee: Sergey Beryozkin
>             Fix For: 3.1.8, 3.0.11, 3.2.0

>
> The http request:
>  POST /dubbott-demo-provider/v1.0/users/beanparam HTTP/1.1
> HOST: localhost:8080
> accept: text/plain
> content-type: application/x-www-form-urlencoded
> content-length: 12
> pageIndex=99
> The resource method returns null:
> {code:java}
>     public String beanParam(@Context HttpServletRequest req, String ak) {
>         String pageIndex = req.getParameter("pageIndex")    
>         return pageIndex;
>     }
> {code}
> From the servlet 3.1 API doc:
> String javax.servlet.ServletRequest.getParameter(String name)
> Returns the value of a request parameter as a String, or null if the parameter does not exist. Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.
> if we add below servlet filter:
> {code:java}
> 	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
> 	        System.out.println(request.getParameter("pageIndex") );
> 		chain.doFilter(request, response);
> 	}
> {code}
> The output is "99" the response is the same "99".
> As a conclusion the CXF HttpServletRequest doesn't comply the Servlet 3.1 API Spec.
