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:

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?

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.

I got a simple demo project with embedded Jetty and JSF (Primefaces). The problem is that my beans are not loaded at all.

The class to start the embedded server is /src/main/JettyRunner.java. The main method is:
InetSocketAddress address = InetSocketAddress.createUnresolved("localhost", 8080);
Server server = new Server(address);
WebAppContext wac = new WebAppContext();
wac.setContextPath("/ui");
wac.setWelcomeFiles(new String[] { "index.xhtml" });
String webappDir=JettyRunner.class.getClassLoader().getResource(".").toString();
wac.setBaseResource(new ResourceCollection(new String[] {
webappDir+"../../src/main/webapp","./target" }));
server.setHandler(wac);
server.setStopAtShutdown(true);
server.start();
server.join();
The messages in postConstruct or the Constructor are not printed at all. Accessing a property of this bean in my xhtml gives no error and just prints nothing.
Even if I access a bean that does not exist, there's no error message.
Why are my beans not loaded?
After three days I finally found the answer myself:
Just added the line
wac.setResourceAlias("/WEB-INF/classes/", "/classes/");
to my runner class. Now everything works as expected.
Try adding the #Named annotation to your bean. This annotation makes the managed bean accessible through the EL. Then change
<h:outputText value="HelloBean.name"/>
to
<h:outputText value="#{HelloBean.name}"/>
in /src/main/webapp/index.xhtml

How to use PrimeFaces p:fileUpload? Listener method is never invoked or UploadedFile is null / throws an error / not usable

Closed 7 years ago.
I tried to upload a file with primefaces into my tomcat7 server. I'm using primfaces4. file upload listener doesn't call handleFileUpload and hiii not apeared in console
my bean is this:
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;

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;
}
public void handleFileUpload(FileUploadEvent event) {
UploadedFile file = event.getFile();
U.wl("hiii");
//application code
}
}

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">

<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;

Do this because I also got same problem before
public void handleFileUpload(FileUploadEvent event) {
System.out.println("calling file upload...");
File targetFolder = new File(Properties.File_Uploaded_path
+ File.separator);
if (!targetFolder.exists()) {
targetFolder.mkdirs();
}
try {
InputStream inputStream = event.getFile().getInputstream();
OutputStream out = new FileOutputStream(new File(targetFolder,
event.getFile().getFileName()));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = inputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
inputStream.close();
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("file upload after catch..");
employeeFileUploadPaths[employeeFileCount] = targetFolder
.getAbsolutePath()
+ File.separator
+ event.getFile().getFileName();
System.out.println("empFileUploadPaths[check]"
+ employeeFileUploadPaths[employeeFileCount]);
employeeFileCount++;
FacesMessage msg = new FacesMessage("Succesful", event.getFile()
.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
System.out.println("last line of file upload....");

Your references to the managed bean are wrong. Use the name as written in the name attribute of the #ManagedBean annotation.
So replace:
<p:imageCropper value="#{imageCropperBean.croppedImage}"
image="/detroit-nights.jpg" />
<p:graphicImage id="localCroppedImage"
value="#{imageCropperBean.newFileName}.jpg" />
with
<p:imageCropper value="#{imageCrop.croppedImage}"
image="/detroit-nights.jpg" />
<p:graphicImage id="localCroppedImage"
value="#{imageCrop.newFileName}.jpg" />
(You did it correctly for the p:commandButton).
Since yesterday I struggle with uploading a file in my jsf web application. The tutorials (one from balusC, the other one from some offical java-tutorial page) I found were very good, but somehow it still won't run. I guess there's something wrong with the web.xml, because that were the answers I found on google, but still no good results for me.
Now in details:
Firstly: I build a new project just to test the upload, so if there are too many libraries (if there is s.th. like that), pls let me know.
Secondly: it's a course projekt at my university, so there are some things, I have to use, like the h2-database and the glassfish application server.
libraries I use:
commons-el-1.0.jar
commons-fileupload.1.2.1.jar
commons-io-1.3.2.jar
commons-logging.1.1.1.jar
tomahawk20-1.1.10.jar
h2-1.2.141.jar

Like I said, it's just the tutorial I put together; the name of the file is shown in the textfield, but when hitting submit, there's just the exception.
Thanks in advance.
EDIT: I just thought it might be useful to know that work with the 1.6.0jdk.
I had the same problem, but worked in linux and fail in windows. To pass over this issue i found this solution:
Do not forget to add the "enctype" attribute to your Form and set this attribute to "multipart/form-data".
<h:form enctype="multipart/form-data">

and faces-config.xml :

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"

The problem is that upon the click on the button, the locale is not changed. Upon manual refresh, the correct locale has been shown.
Could you please help me with this. Have to say that the same page, implemented in pure JSF 2.0 (icefaces excluded) is working perfectly.
Thanks
You need to re-render the entire page or better, fire a synchronous request instead of an asynchronous (ajaxical) request which would only render the page partially.
