Primefaces fileUploadListener not working

jsf, jsf-2, primefaces

Solution

Finaly it worked, I used simple type of upload. Important thing:

1- `<h:head></h:head>` was necessary

2- this is necessary in web.xml:

 <context-param>
    <param-name>primefaces.UPLOADER</param-name>
    <param-value>commons</param-value>
  </context-param>

 <filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

3- in `h:form` it's important to write `enctype="multipart/form-data"`

4- `ajax="false"` for the command button is necessary

I used the simple upload type:

<?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:f="http://java.sun.com/jsf/core"
xmlns:t="http://myfaces.apache.org/tomahawk"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:head></h:head>
<h:form enctype="multipart/form-data">
<p:fileUpload value="#{pinBean.file}" mode="simple" />
<p:commandButton value="Submit" ajax="false"/>
</h:form>

</html>

and my bean is:

package Pin;
import javax.enterprise.context.SessionScoped;
import javax.faces.bean.ManagedBean;

import org.primefaces.component.fileupload.FileUpload;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.UploadedFile;

import Util.U;
@ManagedBean(name="pinBean")
@SessionScoped
public class PinBean{
    private UploadedFile file;
    public PinBean(){

        U.wl("Start");
    }
    public UploadedFile getFile() {
        U.wl("get");
        return file;
    }

    public void setFile(UploadedFile file) {
        U.wl("set");
            this.file = file;
        }
}

and my web.xml

    This parameter tells MyFaces if javascript code should be allowed in
    the rendered HTML output.
    If javascript is allowed, command_link anchors will have javascript code
    that submits the corresponding form.
    If javascript is not allowed, the state saving info and nested parameters
    will be added as url parameters.
    Default is 'true'</description>

    <param-value>true</param-value>
  </context-param>
  <context-param>
    <description>
    If true, rendered HTML code will be formatted, so that it is 'human-readable'
    i.e. additional line separators and whitespace will be written, that do not
    influence the HTML code.
    Default is 'true'</description>

  <context-param>
    <description>
    If true, a javascript function will be rendered that is able to restore the
    former vertical scroll on every request. Convenient feature if you have pages
    with long lists and you do not want the browser page to always jump to the top
    if you trigger a link or button action that stays on the same page.
    Default is 'false'
