PrimeFaces p:fileUpload does not invoke method

Question

I'm trying to use PrimeFaces <p:fileUpload>. I have it setup, very much the same as the showcase example, but it does not work. I never get the successful message. I get no errors or anything.

Here's my web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

        <servlet-name>Faces Servlet</servlet-name>

            <param-value>C:\etc</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>PrimeFaces FileUpload Filter</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>faces/index.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

Here's the view:

<?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:p="http://primefaces.org/ui">

    <h:head></h:head>

    <h:form enctype="multipart/form-data">
        <p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}"
                      mode="advanced" 
                      update="messages"
                      sizeLimit="100000" 
                      allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>

        <p:growl id="messages" showDetail="true"/>
    </h:form>

</html>

    </h:form>
  </h:body>

Here's the bean:

package fileUpload;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.context.FacesContext;

import org.primefaces.event.FileUploadEvent;

@ManagedBean(name = "fileUploadController")
public class fileUploadController {

    private String destination = "c:\test";

    public void upload(FileUploadEvent event) {
        FacesMessage msg = new FacesMessage("Success! ", event.getFile().getFileName() + " is uploaded.");
        FacesContext.getCurrentInstance().addMessage(null, msg);
        // Do what you want with the file        
        try {
            copyFile(event.getFile().getFileName(), event.getFile().getInputstream());
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    public void copyFile(String fileName, InputStream in) {
        try {


            // write the inputStream to a FileOutputStream
            OutputStream out = new FileOutputStream(new File(destination + fileName));

            int read = 0;
            byte[] bytes = new byte[1024];

            while ((read = in.read(bytes)) != -1) {
                out.write(bytes, 0, read);
            }

            in.close();
            out.flush();
            out.close();

            System.out.println("New file created!");
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
    }
}

What have I missed out?

Hi there i have tried following the sets in that, but still i can not upload the image, it will let me upload it but there is no successful message or anything so i do not think it is uploading it — user1924104, Dec 23 '12 at 21:13
Okay, you have thus also Commons-FileUpload and Commons-IO in webapp's runtime classpath? Your view is by the way quite strange. The form is not in the body. Is this careless preparation for the question or does it reflect the real code? — BalusC, Dec 23 '12 at 21:16
i have added Commons-FileUpload and Commons-IO into Web-INF/lib, i have not done anything else with these apart from include them here, i read this should be enought, should i do anything else with these ? i am using netbeans and glassfish — user1924104, Dec 23 '12 at 21:19

The exception is self-explaining.

javax.el.MethodNotFoundException: /index.xhtml @15,63 fileUploadListener="#{fileUploadController.handleFileUpload(event)}": Method handleFileUpload not found

This method does indeed not exist. It's instead this one:

public void upload(FileUploadEvent event) {

Use either #{fileUploadController.upload} or rename the method to handleFileUpload.
