p:fileupload doesnt work on Websphere 8 - file-upload

I wonder if anyone managed to get Primefaces' p:fileupload component work on Websphere Application Server 8.
I use Primefaces 2.2.1 version.
JSF code:
<h:form enctype="multipart/form-data">
<p:fileUpload
fileUploadListener="#{mailBean.handleFileUpload}"
multiple="true"
label="choose"
allowTypes="*.jpg;*.png;*.gif;"
description="Images"/>
</h:form>
Managed Bean code:
public void handleFileUpload(FileUploadEvent event)
{
files.add(event.getFile());
logger.info("File uploaded into MailBean: " + event.getFile());
System.out.println("File uploaded into MailBean: " + event.getFile());
}
Web.xml filter: (Servlet 3.0)
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
<init-param>
<param-name>thresholdSize</param-name>
<param-value>51200</param-value>
</init-param>
<init-param>
<param-name>uploadDirectory</param-name>
<param-value>c:/temp/pf</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
The component says HTTP error and turns into red, on the console I get a ViewExpiredException by Myfaces:
Caused by: javax.faces.application.ViewExpiredException: /createmail.xhtml
No saved view state could be found for the view identifier: /createmail.xhtml
at org.apache.myfaces.lifecycle.RestoreViewExecutor.execute(RestoreViewExecutor.java:128)
at org.apache.myfaces.lifecycle.LifecycleImpl.executePhase(LifecycleImpl.java:171)
at org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118)
at javax.faces.webapp.FacesServlet.service(FacesServlet.java:189)
I even tried with two other versions of Mojarra instead of Myfaces, but I got errors (2.1: handler doesnt get invoked, 2.0.3: viewexpired)

Did u have the .jars and the web.xml config (remove "c:", the default is that route) ? I had the same problem but then i restarted my WAS 8.5 and it worked.

I'm using Websphere 7 with JSF 2.0 with Mojarra 2 and PrimeFaces 3.4.2 (common-fileupload-1.2.2.jar and common-io-1.3.2.jar)
I see the fileUpload don't call the bean in WebSphere.
I see the bar that load the file but don't arrive the event on the managedBean.
It seems as if some other filter in Websphere capture the HTTP request and you can't get data sent by fileUpload because are just consumed :(

Issue with enabing CORS and solving 403 Forbidden error

I try to solve the error 403 Forbidden that I get when sending requests to my GeoServer. To debug the process, I use Network tab from Inspect option in Chrome (I also tried Firefox). This is the error that I see in the Network tab.
XMLHttpRequest cannot load
http://localhost:8080/geoserver/square/ows?service=WFS&version=1.1.0&requ…ture&typeName=square:InformationStores&outputFormat=application%2Fjson.
Response to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'http://localhost:5601' is therefore not allowed
access. The response had HTTP status code 403.
My GeoServer 2.10.4 is CORS enabled according to multiple tutorials that I found on this topic. However, the error message that I receive seems to be related to proxy.
I spent so much time trying to solve this issue, so finally, I am absolutely lost. I tried a lot of things, but nothing has worked.
This is the configuration file of GeoServer to which I send request:

Instead of adding to the web.xml, simply uncomment the two CORS related blocks that are already in there.

PrimeFaces 4.0 FileUpload works with Mojarra 2.2 but not MyFaces 2.2

I am having an interesting problem with the PrimeFaces 4.0 final FileUpload element.
I am trying to run:
PrimeFaces 4.0 final
Apache MyFaces 2.2.0-beta
Tomcat 7.0.27
I have a very simple setup right now,
XHTML page:
<?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">

<h:head>
</h:head>
<h:body>
<h:form>
<p:fileUpload
fileUploadListener="#{fileUploadController.handleFileUpload}"
mode="advanced" update="messages" sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
<p:growl id="messages" showDetail="true" />
</h:form>
</h:body>
</html>
With this backing bean:
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.context.FacesContext;
import org.primefaces.event.FileUploadEvent;
#ManagedBean
#RequestScoped
public class FileUploadController
{
public void handleFileUpload(FileUploadEvent event)
{
FacesMessage msg = new FacesMessage("Succesful", event.getFile()
.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
When selecting a file and uploading it, nothing happens.
The upload submit succeeds with the following response:
<?xml version="1.0" encoding="UTF-8"?><partial-response><changes><update id="j_id__v_0:javax.faces.ViewState:1"><![CDATA[2C7ZmtwSmrlbgI/wJLI2CLBaMOQP9R/pYkIXpHlXkhSKIhtfFM0sx0HmL8o9MQY2MdHXg4t1vUjJbUYkAdFBmOQUaFy7hFhPr34Za4hOuLW4CPNx]]></update></changes></partial-response>
but no message is displayed, and if I set a breakpoint, it does not get hit.
If, however, I pull out MyFaces 2.2.0-beta and put in Mojarra 2.2.0, everything works as expected.
I would prefer to continue to use MyFaces as it is what I've used in the past, so if anyone has any ideas as to a patch to get this to work, it would be much appreciated.
Thank you

Update
It seems that Myfaces 2.2.0-beta has problems using the Part API present in servlet 3.x.
udaykiran pulipati has part of a solution with using web the web.xml filters that PrimeFaces 3.x required and the commons file upload & commons io jars, however, we also need to add the following context-param to the web.xml or the filters get ignored :
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
This will force PrimeFaces to use the commons library which fixes the problem
That being said, I would still like to know why MyFaces can't seem to use the servlet Part API if anyone has any ideas. I suspect it may have to do with my Tomcat version as I am only on 7.0.27, but I doubt that.
Mention below filters in web.xml file for uploading a file using PrimeFaces
<!-- PrimeFaces FileUpload Filter -->
<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>
and add jars to lib folder. PrimeFaces needs below jars for fileuploading.
commons-fileupload-1.3.jar,
commons-io-2.4.jar
Recently it was found a similar issue with a better description in MYFACES-3835. It was a problem related to webkit browsers that only appears when the ajax response is large enough. It has been already fixed.
udaykiran pulipati's answer motivated me to replace commons-fileupload-1.2.2.jar with commons-fileupload-1.3.jar in my project, but that didn't solve the issue for me, as I'm using MyFaces 2.2, PrimeFaces Elite 4.0.8, and TomEE 1.6.1-snapshot.
Also, per udaykiran pulipati's answer, I already added PrimeFaces FileUpload filter config to my web.xml, many months ago.
So, I looked at PrimeFaces 4.0 user guide, and recognized something 'new' that could be specified in web.xml. So, I added the following to my web.xml,
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
and finally, PrimeFaces (Elite) 4.0.x FileUpload works with MyFaces 2.2.

File upload doesn't work with PrimeFaces 4.0, JSF Mojarra 2.2.3 and Wildfly Beta 1

I have a web application running on:

I have the same issue with Wildfly 8.1, PrimeFaces 5.1, Pretty faces and file upload. There is a HACK to make this work in Tomcat, but I can't find one in undertow. PrettyFaces appears to be doing something bad to multipart post requests that prevents them from working correctly... They seem to be pushing it back to Undertow/Wildfly because the hack exists in Tomcat instead of fixing the actual issue.
Wildfly Discussion: http://ocpsoft.org/support/topic/pretty-primefaces-fileupload/
Tomcat Hack: http://ocpsoft.org/support/topic/split-prettyfaces-anchor-with-primefaces-file-upload-not-working/
I'm road blocked on this and I can't really extract either PrettyFaces, PrimeFaces-Fileupload (I need background ajax/html5 uploading) or Wildfly... Anyone with a suggestion other than "use an iframe/simple mode" would be much appreciated.

Unknown Property Error at Primefaces FileUpload

I am using PF 3.0.RC1 / NetBeans 7.0.1 and when I try to set fileUploadListener for fileUpload component , NetBeans gives this warning "Unknown Property 'handleFileUpload' " at leftmost of line.
In debug mode when I use fileUpload , it don't call handleFileUpload method and nothing becomes.
What can I do for this problem ?
The code in the xhtml page :
<p:fileUpload fileUploadListener="#{BDS_System.handleFileUpload}" mode="advanced"
sizeLimit="500000" allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
The code in the managed bean :
public void handleFileUpload(FileUploadEvent event) {
String fileName = event.getFile().getFileName();
byte[] fileBytes = event.getFile().getContents();
...
}
Solved and solution :
Adding
<h:form enctype="multipart/form-data">
and two libraries ,commons-fileupload and commons-io .For maven projects ;
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId> commons-fileupload</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId> commons-io</artifactId>
<version>2.1</version>
</dependency>
my guess that it is that just like in BalusC answer in this thread: "Unknown Property" the error message of netbeans is nonsense , I think you forgot something in the fileupload config , like the
Getting started with FileUpload
First thing to do is to configure the fileupload filter which parses the multipart request. FileUpload filter should map to Faces Servlet.
<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>
and make sure to add enctype to your form like this:
<h:form enctype="multipart/form-data">
if all of the above wont help , take a look at BalusC answer in here: How to use PrimeFaces p:fileUpload

Spring Webflow Application + Primefaces, Fileupload does not work, HTTP Error or/and IO Error

we are developing a JSF spring webflow web application and we are trying to use the primefaces fileupload widget. primefaces works fine, the widgets get rendered correctly. however the fileupload is not working. the handlefileupload function in the backingbean FileUploadController is never called. other primefaces components for example a button can call functions in that bean, so it gets initialized correctly. below you find our configuration. currently we are developing in eclipse and deploying the web app with maven and run the app with a jetty server directly in eclipse. deploying the .war on tomcat didnt work either.
Problem:
after file selection and clicking on upload the widget is giving either the error 'IO Error' or 'HTTP Error'
some data is transfered to the server (we sniffed the network traffic)

Thanks in advance. We hope someone can help us :)
use this filter instead
<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>Spring MVC Dispatcher Servlet</servlet-name>
</filter-mapping>
There is and error or you have copied it wrong from your's xhtml file
<h:form id="mainForm" enctype="multipart/form-data" prependid="false" >
<p:fileUpload id="fileUp" fileUploadListener="#fileUploadController.handleFileUpload}"
description="Images" /></h:form>
The "{" is missing before "fileUploadController.handleFileUpload}" should be:
<h:form id="mainForm" enctype="multipart/form-data" prependid="false" >
<p:fileUpload id="fileUp" fileUploadListener="#{fileUploadController.handleFileUpload}"
description="Images" /></h:form>
