                <blockquote id="blockquote" style="display:none" cite="#"><span id="quote">&#8220; <h:outputText value="#{wiseWordHome.instance.quote}" /> .&#8221;</span><br /><br /><span id="author">&#8212;<h:outputText value="#{wiseWordHome.instance.author}" /></span>
                </blockquote>
 
        <rich:effect name="showDiv" for="blockquote" type="Appear" params="delay:1.8, duration:0.5"></rich:effect>
        <rich:effect name="hideDiv" for="blockquote" type="Fade" params="delay:8.0, duration:2.0"></rich:effect>

                <rich:effect for="window" event="onload" type="Appear" params="targetId:'blockquote',delay:1.8, duration:0.5" />
                <rich:effect for="window" event="onload" type="Fade" params="targetId:'blockquote',delay:7.0, duration:1.0" />
        
           <a4j:region>
            <h:form>
                <a4j:poll id="quotesPoll" interval="10000" enabled="true" oncomplete="hideDiv();showDiv();" ignoreDupResponses="true" eventsQueue="quotesQueue"></a4j:poll>
            </h:form>
        </a4j:region>
                                
     
        </div>

@Entity
@Table(name = "wise_word")
public class WiseWord implements java.io.Serializable {

        private Integer id;
        private String quote;
        private String author;

        public WiseWord() {
        }

        public WiseWord(String quote, String author) {
                this.quote = quote;
                this.author = author;
        }

        @Id
        @GeneratedValue(strategy = IDENTITY)
        @Column(name = "id", unique = true, nullable = false)
        public Integer getId() {
                return this.id;
        }

        public void setId(Integer id) {
                this.id = id;
        }

        @Column(name = "quote", length = 65535)
        @Length(max = 65535)
        public String getQuote() {
                return this.quote;
        }

        public void setQuote(String quote) {
                this.quote = quote;
        }

        @Column(name = "author", length = 50)
        @Length(max = 50)
        public String getAuthor() {
                return this.author;
        }

        public void setAuthor(String author) {
                this.author = author;
        }
