The managed bean is:

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;  
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.UploadedFile;  
@Component
@ManagedBean
@SessionScoped
public class FileUploadController {
      public void handleFileUpload(FileUploadEvent event) {
        FacesMessage msg = new FacesMessage(“Succesful”, event.getFile().getFileName() + ” is uploaded.”);
        FacesContext.getCurrentInstance().addMessage(null, msg);
        //get uploaded file from the event
        UploadedFile uploadedFile = (UploadedFile)event.getFile();

        //create an InputStream from the uploaded file
        InputStream inputStr = null;
        try {
            inputStr = uploadedFile.getInputstream();
        } catch (IOException e) {
            //log error
        e.printStackTrace();
        }

        //create destination File
        String destPath = “D:\fbm\user\”+event.getFile().getFileName();
        File destFile = new File(destPath);

        //use org.apache.commons.io.FileUtils to copy the File
        try {                  
            FileUtils.copyInputStreamToFile(inputStr, destFile);
        } catch (IOException e) {
            //log error
        e.printStackTrace();
        }
    }
}

 In the web.xml add:

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>
        org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
