How to upload image to database using Richfaces and JPA

Question

I am developing a web app on JBOSS AS 7 using Richaces 4, SEAM and JPA. I can not get rich:fileUpload working. I have no idea how to make it. When uploading image through rich:fileUpload, I need it to be inserted into the database. What I did right now:

1. I have an .xhtml page where there is a form for Uploading files (used one from Richfaces demo);
2. Created an entity bean UploadedImage.java (with @Lob annotation for image column);
3. DAO class to persist uploadedimage using entitymanager;
4. And UploadBean.java for view to connect it with EJB project;

If anyone will have the same issue, here is how to get it working:

Upload.xhtml (contains form for image upload):

<rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
                        stopButtonClass="file-upload-stop-button"
                        addButtonClass="file-upload-button" listHeight="0" listWidth="0"
                        id="upload" acceptedTypes="jpg, gif, png, bmp" allowFlush="true" maxFileQuantity="10">
                        <a4j:ajax event="uploadcomplete" execute="@none"
                            render="info, imgs" />
                    </rich:fileUpload>

FileUploadBean.java (delivering data to ejb class):

@Named()
@RequestScoped
public class FileUploadBean implements Serializable {

    private static final long serialVersionUID = 1L;


    @Inject
    private CMSDao cms;

    private Integer pid;
    private String name;
    private String aname;
    private byte[] data;


    public FileUploadBean() {}
    private ArrayList<UploadedImage> files = new ArrayList<UploadedImage>();
    private List<UploadedImage> filess;

    public void listener(FileUploadEvent event) throws Exception {
            UploadedFile item = event.getUploadedFile();
            UploadedImage file = new UploadedImage();
            file.setName(item.getName());
            file.setData(item.getData());
            files.add(file);
            cms.insertImg(file);

        }
    //getters and setters

EJB class:

  public void insertImg(UploadedImage img)  {
            em.persist(img);
            em.flush();
        }

UploadedImage.java (entity bean):

@Entity
@Table(name="photo")
public class UploadedImage implements Serializable {
    private static final long serialVersionUID = -8192553629588066292L;
    @Id
    @GeneratedValue
    @Column(name="pid")
    private Integer pid;
    @Column(name="name")
    private String name;
    @Column(name="aid")
    private String aname;
    @Lob
    @Column(name="data")
    @Basic(fetch = FetchType.LAZY)
    private byte[] data;
// getters and setters
