Simple File Upload File is null

[sence]

Good morning,

if we choose a file and hit the upload button, the "upload" function is executed, but the variable file is null.
i can see on the harddisk, that there are 4 .tmp files (when uploading one file)

view:

Code: Select all

<h:form id="fu_form" enctype="multipart/form-data">  	
	<p:fileUpload id="fu_inserat_bilder" fileUploadListener="#{simpleUploadController.file}" mode="simple" label="Bilder auswählen" sizeLimit="10240000" allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
	<p:commandButton value="hochladen" action="#{simpleUploadController.upload}" ajax="false" icon="ui-icon-arrow-u"/>
</h:form>

SimpleUploadController:

Code: Select all

@ManagedBean
public class SimpleUploadController {

	public SimpleUploadController() {
		
	}
	
    private UploadedFile file;  
    
    public UploadedFile getFile() {  
        return file;  
    }  
  
    public void setFile(UploadedFile file) {    	
        this.file = file;         
    }  

   public void upload() {  
    	System.out.println("Starting upload...");
    	if(file != null) {
            System.out.println("File is available");
        }else
        System.out.println("File is empty");
  }
}

Web.xml:

Code: Select all

 <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>1</param-value>
    </init-param>    
  </filter>
  <filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
  </filter-mapping>  
 <context-param>
   <param-name>primefaces.UPLOADER</param-name>
   <param-value>auto</param-value>
</context-param>

Note: thresholdSize is set to 1, because all files should be placed on harddisk instead of memory

Hi,

Here is my setup that eventually worked. Spent quite some time trying to figure it out even it looks very simple.
pom.xml
<!-- JSF library -->
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.1.7</version>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.7</version>
</dependency>
<!-- Primefaces library -->
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>5.0</version>
</dependency>
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>Spring MVC Servlet</servlet-name>
</filter-mapping>
view.xhtml
<h:form id="fileUploadForm" enctype="multipart/form-data">
<p:fileUpload value="#{repositoryController.uploadFile}" mode="simple" />
<p:commandButton value="Upload" ajax="false" actionListener="#{repositoryController.upload}"/>

</h:form>
In controller I have similar code.
