[OmniFaces utilities 2.0] Get the HTTP request URL with query string

---

[OmniFaces utilities] The getRequestURLWithQueryString() method returns the HTTP request URL with query string. This is the full request URL with query string as the enduser sees in browser address bar.

---

Method:

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. http://localhost:8080/MyApp/ MyServlet?tech=JSF&lib=OmniFaces

  String requestURL = Servlets.getRequestURLWithQueryString(request);

 }

 ...

}

·         in JSF, when FacesContext is available use, Faces#getRequestURLWithQueryString(), or more clumsy (not recommended):

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. http://localhost:8080/MyApp/faces/index.xhtml?tech=JSF&lib=OmniFaces

// Note: in order to preserve the query parameters over a JSF POST you may need, <o:form includeRequestParams="true"> 

String requestURL = Servlets.getRequestURLWithQueryString(request);
