UTF-8 in PrimeFaces 3.x - jsf

I have a very simple application,there is an inputtext in my index page and a button to go to page2.xhtml.
<h:body>
<h:form>
<h:inputText value="#{mainBean.testValue}"/>
<p:commandButton update="myoutput" value="ajax call" ajax="false"/>
<p:separator />
<h:commandButton action="#{mainBean.gotoPageTwo}" value="goto Page2"/>
<br/>
<h:outputText value="#{mainBean.testValue}" id="myoutput"/>
</h:form>
</h:body>
</html>
I tested this application with PrimeFaces 2.2.1 and there was no problem.
but after submit each of the above button, my UTF-8 characters will destroy.
I tested filter but it don't work.
Is it a bug in PrimeFaces 3.x?
Can any body solve this problem?

The web.xml example of the answer you found at PrimeFaces forum is incomplete. The <filter-mapping> is missing. Without that, the filter won't even run at all. Add it accordingly
<filter-mapping>
<filter-name>Character Encoding Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
When you're already on Servlet 3.0 (Tomcat 7, Glassfish 3, etc), an alternative is to use just the #WebFilter annotation on the class. Don't forget to remove the filter entry from web.xml.
#WebFilter("/*")
For a background explanation of the cause of this character encoding problem during PrimeFaces 2.x-3.x upgrade, see also Unicode input retrieved via PrimeFaces input components become corrupted

HttpServletRequest.getParameter breaks Primefaces FileUploadFilter? [duplicate]

I'm trying to upload a file using PrimeFaces, but the fileUploadListener method isn't being invoked after the upload finishes.
Here is the view:
<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>
And the bean:
#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);
}
}
I've placed a breakpoint on the method, but it's never called. When using mode="simple" and ajax="false", it is been invoked, but I want it to work in the advanced mode. I'm using Netbeans and Glassfish 3.1.
How to configure and troubleshoot <p:fileUpload> depends on PrimeFaces and JSF version.
All PrimeFaces versions
The below requirements apply to all PrimeFaces versions:
The enctype attribute of the <h:form> needs to be set to multipart/form-data. When this is absent, the ajax upload may just work, but the general browser behavior is unspecified and dependent on form composition and webbrowser make/version. Just always specify it to be on the safe side.
When using mode="advanced" (i.e. ajax upload, this is the default), then make sure that you've a <h:head> in the (master) template. This will ensure that the necessary JavaScript files are properly included. This is not required for mode="simple" (non-ajax upload), but this would break look'n'feel and functionality of all other PrimeFaces components, so you don't want to miss that anyway.
When using mode="simple" (i.e. non-ajax upload), then ajax must be disabled on any PrimeFaces command buttons/links by ajax="false", and you must use <p:fileUpload value> with <p:commandButton action> instead of <p:fileUpload listener>.
So, if you want (auto) file upload with ajax support (mind the <h:head>!):
<h:form enctype="multipart/form-data">
<p:fileUpload listener="#{bean.upload}" auto="true" /> // For PrimeFaces version older than 8.x this should be fileUploadListener instead of listener.
</h:form>
public void upload(FileUploadEvent event) {
UploadedFile uploadedFile = event.getFile();
String fileName = uploadedFile.getFileName();
String contentType = uploadedFile.getContentType();
byte[] contents = uploadedFile.getContents(); // Or getInputStream()
// ... Save it, now!
}
Or if you want non-ajax file upload:
<h:form enctype="multipart/form-data">
<p:fileUpload mode="simple" value="#{bean.uploadedFile}" />
<p:commandButton value="Upload" action="#{bean.upload}" ajax="false" />
</h:form>
private transient UploadedFile uploadedFile; // +getter+setter
public void upload() {
String fileName = uploadedFile.getFileName();
String contentType = uploadedFile.getContentType();
byte[] contents = uploadedFile.getContents(); // Or getInputStream()
// ... Save it, now!
}
Do note that ajax-related attributes such as auto, allowTypes, update, onstart, oncomplete, etc are ignored in mode="simple". So it's needless to specify them in such case.
Also note that the UploadedFile property is declared transient just to raise awareness that this is absolutely not serializable. The whole thing should be placed in a request scoped bean instead of a view or even session scoped one. If this is the case, then you can safely remove the transient attribute.
Also note that you should immediately read and save the file contents inside the abovementioned methods and not in a different bean method invoked by a later HTTP request. This is because technically speaking the uploaded file contents is request scoped and thus unavailable in a later/different HTTP request. Any attempt to read it in a later request will most likely end up with java.io.FileNotFoundException on the temporary file and only cause confusion.
PrimeFaces 8.x or newer
Configuration is identical to the 5.x version info below, but if your listener is not called, check if the method attribute is called listener and not fileUploadListener like as in versions before 8.x.
PrimeFaces 5.x
This does not require any additional configuration if you're using at least JSF 2.2 and your faces-config.xml is also declared conform at least JSF 2.2 version. You do not need the PrimeFaces file upload filter at all and you also do not need the primefaces.UPLOADER context parameter in web.xml. In case it's unclear to you how to properly install and configure JSF depending on the target server used, head to How to properly install and configure JSF libraries via Maven? and "Installing JSF" section of our JSF wiki page.
If you're however not using JSF 2.2 yet and you can't upgrade JSF 2.0/2.1 to 2.2 yet (should be effortless though when already on a Servlet 3.0 compatible container), then you need to manually register the below PrimeFaces file upload filter in web.xml (it will parse the multi part request and fill the regular request parameter map so that FacesServlet can continue working as usual):
<filter>
<filter-name>primeFacesFileUploadFilter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>primeFacesFileUploadFilter</filter-name>
<servlet-name>facesServlet</servlet-name>
</filter-mapping>
The <servlet-name> value of facesServlet must match exactly the value in the <servlet> entry of the javax.faces.webapp.FacesServlet in the same web.xml. So if it's e.g. Faces Servlet, then you need to edit it accordingly to match.
PrimeFaces 4.x
The same story as PrimeFaces 5.x applies on 4.x as well.
There's only a potential problem in getting the uploaded file content by UploadedFile#getContents(). This will return null when native API is used instead of Apache Commons FileUpload. You need to use UploadedFile#getInputStream() instead. See also How to insert uploaded image from p:fileUpload as BLOB in MySQL?
Another potential problem with native API will manifest is when the upload component is present in a form on which a different "regular" ajax request is fired which does not process the upload component. See also File upload doesn't work with AJAX in PrimeFaces 4.0/JSF 2.2.x - javax.servlet.ServletException: The request content-type is not a multipart/form-data.
Both problems can also be solved by switching to Apache Commons FileUpload. See PrimeFaces 3.x section for detail.
PrimeFaces 3.x
This version does not support JSF 2.2 / Servlet 3.0 native file upload. You need to manually install Apache Commons FileUpload and explicitly register the file upload filter in web.xml.
You need the following libraries:
commons-fileupload.jar
commons-io.jar
Those must be present in the webapp's runtime classpath. When using Maven, make sure they are at least runtime scoped (default scope of compile is also good). When manually carrying around JARs, make sure they end up in /WEB-INF/lib folder.
The file upload filter registration detail can be found in PrimeFaces 5.x section here above. In case you're using PrimeFaces 4+ and you'd like to explicitly use Apache Commons FileUpload instead of JSF 2.2 / Servlet 3.0 native file upload, then you need next to the mentioned libraries and filter also the below context param in web.xml:
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value><!-- Allowed values: auto, native and commons. -->
</context-param>
Troubleshooting
In case it still doesn't work, here are another possible causes unrelated to PrimeFaces configuration:
Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has already consumed the request body by e.g. calling getParameter(), getParameterMap(), getReader(), etcetera. A request body can be parsed only once. When you call one of those methods before the file upload filter does its job, then the file upload filter will get an empty request body.
To fix this, you'd need to put the <filter-mapping> of the file upload filter before the other filter in web.xml. If the request is not a multipart/form-data request, then the file upload filter will just continue as if nothing happened. If you use filters that are automagically added because they use annotations (e.g. PrettyFaces), you might need to add explicit ordering via web.xml. See How to define servlet filter order of execution using annotations in WAR
Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has performed a RequestDispatcher#forward() call. Usually, URL rewrite filters such as PrettyFaces do this. This triggers the FORWARD dispatcher, but filters listen by default on REQUEST dispatcher only.
To fix this, you'd need to either put the PrimeFaces file upload filter before the forwarding filter, or to reconfigure the PrimeFaces file upload filter to listen on FORWARD dispatcher too:
<filter-mapping>
<filter-name>primeFacesFileUploadFilter</filter-name>
<servlet-name>facesServlet</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
There's a nested <h:form>. This is illegal in HTML and the browser behavior is unspecified. More than often, the browser won't send the expected data on submit. Make sure that you are not nesting <h:form>. This is completely regardless of the form's enctype. Just do not nest forms at all.
If you're still having problems, well, debug the HTTP traffic. Open the webbrowser's developer toolset (press F12 in Chrome/Firebug23+/IE9+) and check the Net/Network section. If the HTTP part looks fine, then debug the JSF code. Put a breakpoint on FileUploadRenderer#decode() and advance from there.
Saving uploaded file
After you finally got it to work, your next question shall probably be like "How/where do I save the uploaded file?". Well, continue here: How to save uploaded file in JSF.
You are using prettyfaces too? Then set dispatcher to FORWARD:
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
One point I noticed with Primefaces 3.4 and Netbeans 7.2:
Remove the Netbeans auto-filled parameters for function handleFileUpload i.e. (event) otherwise event could be null.
<h:form>
<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload(event)}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
Looks like javax.faces.SEPARATOR_CHAR must not be equal to _
Putting p:fileUpload inside a h:form solved the problem at my case.
I had same issue with primefaces 5.3 and I went through all the points described by BalusC with no result. I followed his advice of debugging FileUploadRenderer#decode() and I discovered that my web.xml was unproperly set
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>auto|native|commons</param-value>
</context-param>
The param-value must be 1 of these 3 values but not all of them!! The whole context-param section can be removed and the default will be auto
bean.xhtml
<h:form enctype="multipart/form-data">
<p:outputLabel value="Choose your file" for="submissionFile" />
<p:fileUpload id="submissionFile"
value="#{bean.file}"
fileUploadListener="#{bean.uploadFile}" mode="advanced"
auto="true" dragDropSupport="false" update="messages"
sizeLimit="100000" fileLimit="1" allowTypes="/(\.|\/)(pdf)$/" />
</h:form>
Bean.java
#ManagedBean
#ViewScoped
public class Submission implements Serializable {
private UploadedFile file;
//Gets
//Sets
public void uploadFasta(FileUploadEvent event) throws FileNotFoundException, IOException, InterruptedException {
String content = IOUtils.toString(event.getFile().getInputstream(), "UTF-8");
String filePath = PATH + "resources/submissions/" + nameOfMyFile + ".pdf";
MyFileWriter.writeFile(filePath, content);
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO,
event.getFile().getFileName() + " is uploaded.", null);
FacesContext.getCurrentInstance().addMessage(null, message);
}
}
web.xml
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<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>
Neither of the suggestions here were helpful for me. So I had to debug primefaces and found the reason of the problem was:
java.lang.IllegalStateException: No multipart config for servlet fileUpload
Then I have added section into my faces servlet in the web.xml. So that has fixed the problem:
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<multipart-config>
<location>/tmp</location>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>
</servlet>
For people using Tomee or Tomcat and can't get it working, try to create context.xml in META-INF and add allowCasualMultipartParsing="true"
<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
<!-- empty or not depending your project -->
</Context>
With JBoss 7.2(Undertow) and PrimeFaces 6.0 org.primefaces.webapp.filter.FileUploadFilter should be removed from web.xml and context param file uploader should be set to native:
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>native</param-value>
</context-param>
I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jQuery imports (one of them was PrimeFaces's bundled jQuery) which caused conflicts to upload files.
Manually adding / loading jQuery with PrimeFaces results in Uncaught TypeErrors

I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jQuery imports (one of them was PrimeFaces's bundled jQuery) which caused conflicts to upload files.
Manually adding / loading jQuery with PrimeFaces results in Uncaught TypeErrors

Request.getParts is called without multipart configuration. Either add a #MultipartConfig to the servlet, or a multipart-config element to web.xml

I would like to use JSF native fileupload component. With AJAX if possible. But I cannot get it to work.
FileUpload
<h:form enctype="multipart/form-data">
<h:inputFile value="#{bean.file}" required="true"/>
<h:commandButton action="#{bean.importFile()}"/>
</h:form>
I thought the following error should not be present using JSF 2.2.
Request.getParts is called without multipart configuration. Either add
a #MultipartConfig to the servlet, or a multipart-config element to
web.xml
Environment
Glassfish 4.1
Mojarra 2.2.4
Primefaces 5.0
For some [not apparent] reason, the #MultipartConfig that was added to FacesServlet for JSF-2.2 is not kicking in for you. As a result, it's now necessary for you to manually add the multipart configuration to your web.xml like so:
<multipart-config>
<location>/tmp</location>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>

primefaces fileupload not showing up

on my 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>
on my xhtml
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{testController.handleFileUpload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
already imported the commons-fileupload, and commons-io libraries.
using JSF 2.0 and Primefaces 3.5
my problem is, the upload layout in not displaying, theres no buttons for choose,upload nor cancel.
code reference is here: http://www.primefaces.org/showcase/ui/file/upload/single.xhtml
Maybe the rest of your page has problems.
Do you have h:head instead of head and h:body instead of body? If you don't that could cause your components not to render properly.
I would leave this as a comment, but I don't have enough points yet
Are you using MyFaces or Mojarra? The Primefaces Team develop thinking only to work on Mojarra, their Ajax implementation for example didn't work with composite:clientbehavior.
Try with Mojarra.
I had the same problem. I spent a few days on this and finnaly I realize that I had in my lib RICHFACES and PRIMEFACES so I decided to delete RICHFACES and the component started to render right! Take a look at this...

PrimeFaces file upload stopped working

I have a problem with file upload using PrimeFaces. I went through old post here on StackOverflow a didn't find anything useful. Strange thing is that I made it work yesterday but I started my server now and it's working anymore. It's giving me NPE when I try to access the uploaded file.
So I downloaded commons-fileupload-1.2.2.jar and commons-io-1.4, put them in my classpath, configured my web.xml like this
<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>
My form in xhtml page contains one field with description, one combo box and field upload element
<h:form enctype="multipart/form-data">
<p:panel header="#{submitProjectPage['header']}">
<h:panelGrid columns="2">
#{submitProjectPage['chooseProject']}
<p:selectOneMenu value="#{submitProjectBean.project}" converter="projectConverter">
<f:selectItems value="#{submitProjectBean.studentsProjects}" />
</p:selectOneMenu>
And finally my bean is RequestScoped and has this method
private UploadedFile projectFile;
public void submitProject(ActionEvent event) {//also tried without parameter
project.setFile(projectFile.getContents());
project.setStatus(StatusEnum.DELIVERED);
daoBean.update(project);
}
#{submitProjectPage['submitInformation']}
<p:inputTextarea rows="10" value="#{submitProjectBean.s}"/>
#{submitProjectPage['file']}
<p:fileUpload value="#{submitProjectBean.projectFile}" mode="simple" />
<p:commandButton ajax="false" value="#{submitProjectPage['submit']}"
actionListener="#{submitProjectBean.submitProject}" />
</h:panelGrid>
</p:panel>
I am sure I have my imports right, there is also a setter for projectFile field so I really don't know where could be the problem. I am using PrimeFaces v 3.01
Thanks for help
I found a solution, the thing was that Glassfish for some reason didn't deploy the apache libraries, so I removed them from classpath, added them again and it magically works:-)
So maybe it will help somebody:)
