I am developing a Java Web Application with JSF 2.2 and Primefaces. I would like the user can upload a single file; for this, I used Primefaces 6.0 but it is not working and I just found tutorials (and examples) with Primefaces 5.x and it doesn't work either with Primefaces 5.0.
I preffer to work with Primefaces 6.0 but if you can help me with a Primefaces 5.x version, it's okay.
My web.xml is:
<?xml version="1.0" encoding="UTF-8"?>

My bean code is
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.context.FacesContext;
import org.primefaces.model.UploadedFile;
@ManagedBean
@RequestScoped
public class ZipBean{
UploadedFile arch;
public ZipBean() {
}
public void subir() {
try {
FacesContext context = FacesContext.getCurrentInstance();
if (this.arch != null) {
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_FATAL, "PERFECT!","PERFECT!"));
} else {
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_FATAL, "FILE NULL","FILE NULL"));
}
} catch (Exception e) {
System.out.println(e.toString());
}
}
public UploadedFile getArch() {
return arch;
}
public void setArch(UploadedFile arch) {
this.arch = arch;
}
}
My xhtml is:

When I upload a file, the p:grow show the message FILE IS NULL.

Here is an example of how to upload a file using primefaces 5.0; and you do not need commons-fileupload-1.3.1.jar and commons-io-2.4.jar; and also you do not need to change web.xml , and declare growl inside h:form for more information see this How to upload file in primefaces
FileUploadView .java
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.context.FacesContext;
import org.primefaces.model.UploadedFile;
@ManagedBean
public class FileUploadView {
private UploadedFile file;
public UploadedFile getFile() {
return file;
}
public void setFile(UploadedFile file) {
this.file = file;
}
public void upload() {
if(file.getSize() > 0) {
FacesMessage message = new FacesMessage("Succesful", file.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);
}
else{
FacesMessage message = new FacesMessage("Not Succesful", "file is not uploaded");
FacesContext.getCurrentInstance().addMessage(null, message);
}
}
}
