jsf - Primefaces Poll component triggers HTTP OPTIONS and Ajax call is not made -


i writing web app homepage needs refresh every second. decided use primefaces poll component make ajax calls periodically.

however call not made on project base url, such as:

http://localhost:8080

but work correctly, when url describes folder structure:

http://localhost:8080/web/index.xhtml

project structure:

enter image description here

welcome-file in web.xml:

<welcome-file-list>     <welcome-file>/web/index.xhtml</welcome-file> </welcome-file-list>

index.xhtml

<?xml version="1.0" encoding="utf-8"?> <!doctype html         public "-//w3c//dtd xhtml 1.0 transitional//en"         "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"       xmlns:h="http://java.sun.com/jsf/html"       xmlns:p="http://primefaces.org/ui">  <h:head> </h:head> <h:body>          <h:form>         <h:outputtext value="#{counterview.number}" id="counternumber"/>         <p:poll interval="1" listener="#{counterview.increment}" update="counternumber"/>     </h:form>      </h:body> </html>

counterview.java

@component("counterview") @scope("session") public class counterview {      private int number;      public int getnumber() {         return number;     }      public void increment() {         number++;     }  }

further debugging in firebug shows there's http options method called:

enter image description here

but it's not called http://localhost:8080/web/index.xhtml http://web/index.xhtml , it's aborted after time.

i fix problem forcing redirect address http://localhost:8080/web/index.xhtml i'd know what's causing problem , fix more cleanly.

you're setting absolute path welcome file, noted first / in value:

<welcome-file>/web/index.xhtml</welcome-file>

remove relative context path of application:

<welcome-file>web/index.xhtml</welcome-file>
