Question

In my application running on Apache Tomcat 6 I use fileUpload from PrimeFaces 3.0.M3. But it don’t works correctly. When I upload files its appears in upload directory, but event not fired. Can somebody help me?

My view code:

<h:form prependId="false" id="uploadForm" enctype="multipart/form-data">
    <p:fileUpload id="uploadControl" fileUploadListener="#{fileUploadBean.uploadHandler}" mode="advanced" />
</h:form>

FileUploadBean class source:

@ManagedBean
@RequestScoped
public class FileUploadBean implements Serializable {

    private static final Logger logger = Logger.getLogger(FileUploadBean.class);

    private UploadedFile file;

    public void uploadHandler(FileUploadEvent event) throws AbortProcessingException {
        logger.debug("uploadHandler(FileUploadEvent event)");
        logger.debug("Uploaded file: " + event.getFile().getFileName());
    }

    public UploadedFile getFile() {
        return file;
    }

    public void setFile(UploadedFile file) {
        this.file = file;
    }
}

Answer 1

I think your problem is in your web.xml configuration, you have two different filter mappings declared for the File Upload filter, one of them is incorrect:

<filter-mapping>
   <filter-name>PrimeFaces FileUpload Filter</filter-name>
   <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
<filter-mapping>
   <filter-name>PrimeFaces FileUpload Filter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

Instead you need just this:

 <filter-mapping>
   <filter-name>PrimeFaces FileUpload Filter</filter-name>
   <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

You only want to map the file upload filter to the Faces Servlet.
