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
jboss-el-2.0.1.GA.jar
jstl-1.2.jar
jsf-api.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">

I'm trying to validate a form using hibernate validations. The hibernate not let the data be included without the required fields, however, no message was sent in primefaces.
When I sent the form data, they were not included in the database and the screen does not show any error message.
How can i fix that?

Your bean is really not a CDI bean I guess your problem is caused by mixing up the imports. So try
#javax.inject.Named //defaults to "indexMB"
#javax.enteprise.context.RequestScoped
public class IndexMB {
//rest of your class here
}
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
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:

The exception is self-explaining.
javax.el.MethodNotFoundException: /index.xhtml #15,63 fileUploadListener="#{fileUploadController.handleFileUpload(event)}": Method handleFileUpload not found
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 am pretty new at developing in JSF and I am busy building a project that requires file uploads but every time I run the uploader I get a java.lang.NullPointerException could anyone please help me with this problem, I have searched the internet extensively and cannot find a solution that works.
I am using NetBeans 7.1.1 and GlassFish to deploy.
My code is as follows:
I have added the following jars to my library:
primefaces-3.2.jar
commons-io-2.3.jar
commons-fileupload-1.2.2.jar

Your managed bean does not have any scope. This way JSF defaults to #NoneScoped. So a new one is created on every single #{myBean} evaluation in EL. Right now there are effectively two created when you select a file and submit the button. The file is set on the first one and the action method is invoked on the second one (which doesn't have the file at all).
You need to put it in a bit wider scope, e.g. the request scope.
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
#ManagedBean
#RequestScoped
public class MyBean {
// ...
}
By the way, you've there a dangling import javax.enterprise.context.SessionScoped;. This is specific to CDI and would work only when you're managing beans by CDI #Named instead of by JSF #ManagedBean. Make sure that you use the right package for the bean scope. There's namely also a javax.faces.bean.SessionScoped for the case you need a session scoped JSF managed bean.
