        FacesContext context = FacesContext.getCurrentInstance();

        if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
            return new DefaultStreamedContent();

            String id = context.getExternalContext().getRequestParameterMap().get("id");
            imagem = imagemService.findById(Long.valueOf(1));
            StreamedContent sc = new DefaultStreamedContent(new ByteArrayInputStream(imagem.getArquivo()));

  • To ping some user you need to prepend `@` to the name. It does not matter where the bytes come from, database or hard disk. While you did not ask a question it looks like your post is about how to display a dynamic image using StreamedContent and p:graphicImage. Therefore it is likely having a solution within the linked thread. – Selaron Mar 19 '19 at 20:42
