Primefaces FileUpload with PrettyFaces and JSF 2.2.3

问题

I'm having some problems with PrettyFaces on the pages I use <p:fileupload>.

When I disable the PrettyFaces filter on the page, everything works just fine. When I put it back, I can see the HTTP traffic on the webbrowser, but my fileupload handler is never fired.

This is some relevant part of the code.

Any help would be appreciated!

My .xhtml

<h:form id="formImportarSNs" enctype="multipart/form-data">  
<p:fieldset legend="Admin Panel">    
   <p:fileUpload value="#{adminPanelBean.file}" mode="simple"/>                            
   <p:commandButton ajax="false" actionListener="#{adminPanelBean.upload}"            value="confirm" />  

</p:fieldset>  
</h:form>

My backingBean

package br.sgrd.bean;  

import javax.annotation.PostConstruct;  
import javax.annotation.PreDestroy;  
import javax.faces.application.FacesMessage;  
import javax.faces.bean.ManagedBean;  
import javax.faces.bean.ViewScoped;  
import javax.faces.context.FacesContext;  

import org.primefaces.model.UploadedFile;  

@ViewScoped  
@ManagedBean  
public class AdminPanelBean{  

    private UploadedFile file;  

    public void upload() {    
        if(arquivo != null) {    
            FacesMessage msg = new FacesMessage("Succesful", file.getFileName() + "     is uploaded.");    
            FacesContext.getCurrentInstance().addMessage(null, msg);    
        }    
    } 

    // getters/setters/etc

}

        <pattern value="/admin_panel" />  
        <view-id value="/faces/xhtml/admin_panel.xhtml" />  
    </url-mapping>  

</pretty-config>

Edit: Cleaned up some code.

I've found the solution.

Create the context.xml in the META-INF folder and put this code:

<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
</Context>

You can remove the Fileupload Filter from web.xml

Where I found the solution: http://ocpsoft.org/rewrite/docs/faq

And that's why you need to put it: How to use HttpServletRequest#getParts() in a servlet filter running on Tomcat?

If your problem is the size of the file, take a look at: <p:fileUpload> limiting to 2 Mb

回答2:

It does not work very well. Works with upload small files. If the file is a few MB he can not invoke the method. I do not advise using Primefaces + prettyfaces.

If your case is upload small files can work. Remove the primefaces fileupload configuration of web.xml and create the context.xml file as mentioned above.

I did with 'rewrite-servlet-2.0.9.Final.jar'. It worked perfectly with upload small files.

Use in 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>
    <url-pattern>*.jsf</url-pattern> 
</filter-mapping>
