I have a code that make the upload perfectly using primefaces 3.5, but I update the primefaces lib in my project to 4.0 and it doesn´t work any more. Here is the code:
web.xml
<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>

}

I´m using Netbeans 7.4, primefaces 4.0, common io 2.4, common file upload 1.3 and jsf 2.2.
The datas are in the inputStream
Try something like this :
// write the inputStream to a FileOutputStream
OutputStream out = null;
InputStream in = event.getFile().getInputStream();
try
{
out = new FileOutputStream(new File(dirPath, fileName));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = in.read(bytes)) != -1)
{
out.write(bytes, 0, read);
}
out.flush();
} catch (IOException e) {
}
finally
{
out.close();

My Setup:
Mojarra 2.2.12
I have an abstractsubclass of a FacesConverter.
Sometimes JSF initializes the superclass and sometimes it fails on trying to instantiate the abstract subclass.
I allready found a workaround. I removed the abstract keyword and gave the AbstractTestConverter a FacesConverter annotation which isn't used then.
This is my reproduction of the problem:
TestBean.java
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
#ManagedBean
#ViewScoped
public class TestBean {
private boolean testProp;
public boolean getTestProp() {
return testProp;
}
public void setTestProp(boolean test) {
this.testProp = test;
}
}
TestConverter.java
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
#FacesConverter("testConverter")
public class TestConverter implements Converter{
#Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
if (value.equals("Test")) {
return true;
}
return false;
}
#Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
if (((boolean)value)) {
return "Test";
}
return null;
}
}
AbstractTestConverter.java
public abstract class AbstractTestConverter extends TestConverter{
}

Isn't it possible to use an abstract subclass of a FacesConverter?
I'm developing an web application using JSF and I need to make the web available in other languages. I haven't developed the app, I have to continue its development. In some views the following is used:
<f:view locale="#{nuevoProyectoBacking.locale}"/>
<f:loadBundle basename="com.company.resources.resdisenyo" var="rDisenyo"/>
So I've created a new JSF page and done the same:
<?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://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
<ui:composition template="/WEB-INF/templates/template.xhtml">
<f:event type="preRenderView"
listener="#{nuevoProyectoBacking.forwardIfIsNotAdmin}" />
<f:view locale="#{nuevoProyectoBacking.locale}"/>
<f:loadBundle basename="com.appglass.resources.resdisenyo" var="rDisenyo"/>
<ui:define name="top">
<ui:decorate template="/WEB-INF/templates/menuAdministrador.xhtml"></ui:decorate>
</ui:define>
etc
It only works if I remove f:view locale="#{nuevoProyectoBacking.locale}"
nuevoProyectoBacking.java
#ManagedBean
#ViewScoped
public class NuevoProyectoBacking implements Serializable{
definitions
/** Creates a new instance of NuevoProyectoBacking */
public NuevoProyectoBacking()
{
many assignments
locale = LocaleUtil.getIdioma(getCurrentUser().getIdioma());
}
public String getLocale() {
return locale;
}
public void setLocale(String locale) {
this.locale = locale;
}
public Usuarios getCurrentUser()
{
return (Usuarios) getSessionMap().get("currentUser");
}
public Map<String, Object> getSessionMap() {
FacesContext context = FacesContext.getCurrentInstance();
Map<String, Object> sessionMap = context.getExternalContext().getSessionMap();
return sessionMap;
}
}
LocaleUtil
public class LocaleUtil {
public static String getIdioma(Integer idioma){
if(idioma == 0){
return "es_ES";
} else if (idioma == 1) {
return "en_US";
} else if (idioma == 2) {
return "it_IT";
} else if (idioma == 3) {
return "fr_FR";
} else if (idioma == 4) {
return "pt_PT";
} else if (idioma == 5) {
return "ru_RU";
} else if (idioma == 6) {
return "pl_PL";
}else {
return "es_ES";
}
}
}

I don't think the problem is in nuevoProyectoBacking as it is used by another JSF Page and it works well, language too. I have to remove that one and create a new one with a new look and feel.
I've fixed it but I don't know why xDDDD
This is my new JSF page

I've written all the HTML code inside /nuevoProyectoTemplate2 and it works.

Explain me please what's the problem?
It means that CDI couldn't create an instance of TestBean class to satisfy the request. After reviewing your design, it is pretty unclear what you're trying to do. Usually, a CDI bean should not be an EJB. Remove the EJB #Stateful annotation from TestBean and it should work as expected.
In a project with PrimeFaces 3.3, file upload was functioning properly. I removed the Primefaces 3.3 and added 3.5. Since then, I can not function the file upload. Earlier I have added commons-io and commons.fileupload, I was not sure they are still needed, so that I keep these jar files as well.

I also faced the same problem earlier when version changed from 3.3 to 3.5
but end up with 2nd solution given below finally
1st Solution
There is some problem in primefaces advanced file upload
I think mode="simple" is the problem in the p:fileUpload tag
Make mode="advanced" and test it once.
If it works ,fine then
The thing is you are giving mode="simple" and trying to handle in advanced way.
2nd Solution
make your fileupload like below to handle in a simple manner
<p:fileUpload value="#{staffController.file}" mode="simple"/>
<p:commandButton value="Submit" ajax="false" actionListener="#{staffController.upload}"/>
And in your Backing Bean/Controller/staffController
create a property
private UploadedFile file;
//getter setters
And put an upload method like below
public void upload() {
System.out.println("uploading");
if(file != null) {
FacesMessage msg = new FacesMessage("Succesful", file.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
System.out.println("uploaf finished");
}
Hope it helps

Hi Sorry for the late response.
Please check whether you have added file upload filter for the servlet or not in your web.xml.
1)
<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><!-- your FacesServlet Name -->
</filter-mapping>
2)
Add commons-fileupload1.3.jar file in lib folder.
3)
Make sure your whether your form has the enctype attribute or not
<h:form enctype="multipart/form-data"> <!-- enctype tag is important -->
Please check the abouve 3 points .
The event that caused file upload error was not updating primefaces, but GlassFish update from 3.1 to 4.0. When I simply deploy the same application back in GlassFish 3.1, everything worked fine. Thanks
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
