Primefaces p:fileupload component problem
I am using Primefaces 2.0.1 but the FileUpload component is not working properly. It uses JQuery uploadify behind the scenes. This is my web.xml
<?xml version="1.0" encoding="UTF-8"?>

This is my index.xhtml :-

<p:fileUpload auto="false" widgetVar="fileUpl" fileUploadListener="#{NewJSFManagedBean.saveFile}"/>
</h:form>
</h:body>
</html>
I have following libraries in my classpath :-
primefaces 2.0.1
commons-beanutils
commons-beanutils-bean-collection
commons-digestor
commons-fileUpload
commons-io
commons-logging
jhighlight
The file gets correctly uploaded in /tmp but in browser it always says HTTP error. Please help me. It used to work till yesterday. But today i did a fresh installation of Glassfish and it has stopped working.
A filter needs to be added to web.xml. So, add these lines to web.xml
<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>/tmp</param-value> </init-param> </filter> <filter-mapping> <filter-name>PrimeFaces FileUpload Filter</filter-name> <servlet-name>Faces Servlet</servlet-name> </filter-mapping>
To be able to use the Primefaces fileUpload component, a few Apache Commons dependencies also need to be added:
<dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.1</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> </dependency>
I have had some troubles with this component also. I seem to remember that by adding an id to the fileUpload component and/or the form, things started working for me. Worth a try.
i think you are missing enctype="multipart/form-data" in your h:form tag.
I had the same problem. And note that by deleting the cookies from my browser-firefox-and going to upload my application and it worked.
I'm using PRIMEFACES 2.2.1 and the problem is still there: HTTP error when Chrome or Firefox is used; all fine with IE. In my case, this apparently happens due to a reverse proxy shielding the actual server running the application. If the application is used through a direct URL reference (http://server:port/some path), it works fine; if the reverse proxy URL is used, the requests fail. I don't know why this fails in FF and GC and doesn't do so in IE.
