o:graphicImage images not displayed

I've been facing an issue with Omnifaces 2.1.

I have an images type byte[] stored in my database with a declaration java class like this:

 @Lob
    private byte[] image;

In my xhtml file I have a loop on a class that has an image in it: 

<ui:repeat var="listT" value="#{eventBean.listEvents}">                                             
<o:graphicImage value="#{eventBean.getImage(listT.idEvent)}"  dataURI="true" />  
</ui:repeat>

Now in my bean I tried implementing the getImage() function mentioned in the documentation of omnifaces: 

 @ManagedBean
 @ViewScoped
 public class EventBean implements Serializable {

 private static final long serialVersionUID = 1L;
 @EJB
 private EventServiceLocal eventServiceLocal;
 private Event event = new Event();
 private List<Event> listEvents;
 private List<Event> listEventsval;
 private static Event eventSt;
 private UploadedFile file;

 public byte[] getImage(int eventID) {

    return eventServiceLocal.listEventspicture(eventID);
}

When I execute this I gt no image and when I inspect the element, I get this as a result:

 <o:graphicimage value="[B@1aeef88" datauri="true"></o:graphicimage>

when i execute this i got no image and when inspect the element i get this as result :

<o:graphicimage value="[B@1aeef88" datauri="true"></o:graphicimage>

In other words, <o:xxx> tags don't work at all. This is not restricted to <o:graphicImage> alone. All other <o:xxx> tags in the same page would also not work.

That can have 2 causes:

  1. OmniFaces is not installed in webapp.
  2. The o XML namespace is not declared in the XHTML page.

The normal procedure to solve this is:

  1. Add OmniFaces JAR file to /WEB-INF/lib (or let your dependency manager do it).
  2. Add xmlns:o="http://omnifaces.org/ui to some parent element.

To verify the working:

  1. When exporting a WAR file from your project and inspecting it using a ZIP tool, the physical OmniFaces JAR file should be present in /WEB-INF/lib folder and there should be a line like below in server log during deployment:

    INFO [org.omnifaces.ApplicationInitializer] Using OmniFaces version 2.6.8

  2. There should be no <o:xxx> tags anywhere in the generated HTML output.
