[OmniFaces utilities 2.0] Get the HTTP request URI relative to the context root of a web application

---

[OmniFaces utilities] The getRequestRelativeURI() method returns the HTTP request URI relative to the context root of a web application. This is the request URI minus the context path. Note that this includes path parameters.

---

Method:

OmniFaces 2.4 (uses Servlets.getRequestURI())	OmniFaces 2.0

Usage:

inside a servlet filter or even a plain vanilla servlet (basically, when FacesContext is not available):

import org.omnifaces.util.Servlets;

...

@WebServlet("/MyServlet")

public class MyServlet extends HttpServlet {

 protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

  // e.g. /MyServlet

  String relativeURI = Servlets.getRequestRelativeURI(request);

 }

 ...

}

·         in JSF, when FacesContext is available you can use: 

import org.omnifaces.util.Servlets;

...

// or simply use, Faces#getRequest()

Faces Context context = FacesContext.getCurrentInstance();

ExternalContext externalContext = context.getExternalContext();

HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

// e.g. /faces/index.xhtml

String relativeURI = Servlets.getRequestRelativeURI(request);
