Get the request URL in a JSF bean?

Question

How do you get the request URL in a bean backing a JSF page? I\'ve been looking through the FacesContext docs and the best way I could find seems terribly long:

Answer 1

If you ever need to haul the raw Servlet API from under the JSF hoods by the FacesContext, then chances are that you're doing the job at the wrong place. What is it, the functional requirement for which you thought that this is the right solution? Should you maybe not be using a real Servlet class or a Filter instead of a JSF managed bean? Or maybe don't you need the request URL at all because there are better "jsfish" ways to achieve the same?

If you update your question to include the detail about the functional requirement, then we may be able to suggest the right solution.

Update as per your edit: so, you just need it after all in the view side? E.g. #{bean.requestURL}? You can also just grab it from the HttpServletRequest object which is already implicitly available in EL.

When you're on JSP:

${pageContext.request.requestURL}

Or when you're on Facelets:

#{request.requestURL}

And now, how do you need it for JavaScript? Printing as a JavaScript variable? Like so?

var url = '#{request.requestURL}';

If so, you could also just grab window.location for that.

var url = window.location;

No need to clutter the JSF bean with the view specific details.
