[OmniFaces utilities 2.0] Return true if the given HTTP servlet request is a JSF resource request

---

[OmniFaces utilities] The isFacesResourceRequest() method returns true if the given HTTP servlet request is a JSF resource request. I.e. this request will trigger the JSF ResourceHandler for among others CSS/JS/image resources.

---

Method:

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

Usage:

This implementation relies on the fact that a JSF request path that points a resource will contain the ResourceHandler.RESOURCE_IDENTIFIER contract:

·         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 {

  boolean isFacesResourceRequest = Servlets.isFacesResourceRequest(request);

 }

 ...

}

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

import org.omnifaces.util.Servlets;

...

// or simply use, Faces#getRequest()

FacesContext context = FacesContext.getCurrentInstance();

ExternalContext externalContext = context.getExternalContext();

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

boolean isFacesResourceRequest = Servlets.isFacesResourceRequest(request);
