<p:fileUpload> always give me null contents
I'm trying to get working like what is documented in the primefaces user guide, and some posts founded there.
Upload file in JSF primefaces.
the environnement is : javaee full + jpa + jsf 2.2 + primefaces 4 + glassfish v4
I m posting again, because i have tried every sample and suggestion i have found on the web, without success.
I m able, to get the file uploaded name with : event.getFile.getFileName, but the content is always null
-------------Updates----------------------------
My xhtml page :
<h:form enctype="multipart/form-data">
<p:outputLabel value="La photo :"/>
<p:fileUpload fileUploadListener="#{personController.upload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
my managed bean :
@Named(value = "personController")
@SessionScoped
public class PersonController implements Serializable {
/**
* Creates a new instance of PersonController
*/
@Inject
private PersonneFacade personneService;
private Personne current;
private Personne newPerson;
private List<Personne> personnes;
public PersonController() {
}
public List<Personne> getAll(){
return personneService.findAll();
}
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
System.out.println(event.getFile().getFileName());
System.out.println("le fichier " + event.getFile().getContents());
newPerson.setPhoto(event.getFile().getContents());
}

when i m triyng to upload i got on the glassfish output log:
INFO: mdmx.jpg
INFO: le fichier null
any idea about ??
Answer
I have solved this issue like folowing :
The upload worked for me when using : IOUtils.toByteArray(file.getInputstream());
the environnement is : Java EE 7(JPA, EJB, JSF 2.2.4), Glassfish V4, Primefaces 4
i give here the complete example, for reusing.
First : upload.xhtml
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{personController.handleFileUpload}" />
<p:growl id="messages" showDetail="true"/>
</h:form>
Second : PersonController.java (the jsf managed bean) : package com.sos.fso.grh.controllers;
import com.sos.fso.grh.entities.Person;
import com.sos.fso.grh.services.PersonFacade;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.Serializable;
import java.util.List;
import javax.enterprise.context.SessionScoped;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.inject.Inject;
import javax.inject.Named;
import org.apache.commons.io.IOUtils;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.DefaultStreamedContent;
import org.primefaces.model.UploadedFile;
@Named
@SessionScoped
public class PersonController implements Serializable{
@Inject
private PersonFacade personService;
private Person current;
private Person newPerson;
private List<Person> personnes;
public void handleFileUpload(FileUploadEvent event) throws IOException {
UploadedFile file = event.getFile();
System.out.println(file.getFileName());
byte[] foto = IOUtils.toByteArray(file.getInputstream());
System.out.println(foto);
newPerson.setPhoto(foto);
//application code
}
}
Third : the web.xml

if you have an entity bean "person" for example with a @Lob binary attribute, you can fill it with the byte data. to save the image (or file if you need).
to restore it on a
the view.xhtml
<!DOCTYPE html>
<html xmlns="http://www.w3c.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui">
<h:head>
</h:head>
<h:body>
<h:form>
#{personController.current.FName}
<p:panelGrid columns="2">
<p:outputLabel value="Nom :"/>
<h:outputText value="#{personController.current.FName}" />
<p:outputLabel value="Prénom :"/>
<h:outputText value="#{personController.current.LName}" />
<p:outputLabel value="Date de naissance :"/>
<h:outputText value="#{personController.current.birthDate}" />
<p:outputLabel value="photo :"/>
<p:graphicImage value="#{personController.byteToImage(personController.current.photo)}" />
</p:panelGrid>
<p:commandLink value="retour a la liste" action="#{personController.showList}"/>
</h:form>
</h:body>
</html>
and the PersonController Method to restore the image (This code is of BalusC from stackOverFlow )
public DefaultStreamedContent byteToImage(byte[] imgBytes) throws IOException {
ByteArrayInputStream img = new ByteArrayInputStream(imgBytes);
return new DefaultStreamedContent(img,"image/jpg");
}
thanks for everyone helped me.
thanks again
