Description

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:

    public String beanParam(@Context HttpServletRequest req, String ak) {
        String pageIndex = req.getParameter("pageIndex")    
        return pageIndex;
    }

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:

	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
	        System.out.println(request.getParameter("pageIndex") );
		chain.doFilter(request, response);
	}

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.
