PrimeFaces uploadFile is not working - jsf

Question

I'm using PrimeFaces <p:fileUpload>. It does not invoke the listener method. If I add the FileUploadFilter, then I get an exception.
View:
<h:form enctype="multipart/form-data">
<p:fileUpload mode="advanced"
fileUploadListener="#{fileUploadController.upload()}"
allowTypes="/(\.|\/)(gif|jpg|jpeg|gif|png|PNG|GIF|JPG|JPEG)$/"
auto="false" />
</h:form>
Bean:
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());
}
}
}

fileUploadListener="#{fileUploadController.upload()}" is problem here. I reproduced that and I also got an exception Method not found:
You should define fileUploadListener whithout parentheses. When you have added parentheses, expected method in your bean is upload() and not upload(FileUploadEvent event)
