JSF 2 Lifecycle <p>I have this code for BookModel.java:</p> <pre><code>@Entity @Table(name = "BOOK") @NamedNativeQuery(name = "BookModel.findBookTitle", query = "SELECT @rownum:=@rownum+1 'no', m.title, m.author, REPLACE(SUBSTRING_INDEX(m.content, ' ', 30), '&lt;br&gt;', ' '), m.viewed, m.hashid FROM book m, (SELECT @rownum:=0) r WHERE m.title like 'a%'") public class BookModel implements Serializable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "MY_SEQ_GEN") @Column(name = "id", unique = true, nullable = false) private Long id; @NotNull @Size(min = 1, max = 255) @Column(name = "title") private String title; @NotNull @Size(min = 1, max = 255) @Column(name = "author") private String author; } </code></pre> <p>And BookService.java for the business layer:</p> <pre><code>@Stateless public class BookService { @SuppressWarnings("unchecked") public List&lt;BookModel&gt; getBook() { Query query = entityManager.createNamedQuery("BookModel.findBookTitle"); List&lt;BookModel&gt; result = query.getResultList(); return result; } } </code></pre> <p>And BookBean.java for the presentation layer:</p> <pre><code>@ManagedBean(name = "BookBean") @RequestScoped public class BookBean implements Serializable { @EJB private BookService bookService; private DataModel&lt;BookModel&gt; book; public DataModel&lt;BookModel&gt; getBook() { return book; } } </code></pre> <p>And the page book.xhtml:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.prime.com.tr/ui"&gt; &lt;p:dataTable id="bookList" value="#{BookBean.book}" var="book"&gt; ... &lt;/p:dataTable&gt; &lt;/html&gt; </code></pre> <p>My question is: How can I restrict the method <strong>getBook()</strong> in <strong>BookBean</strong> to be executed only once instead of six times - presumably for each phase of JSF lifecycle. Has anyone else come across this before? Please help. Have been stuck on this for the last day without any success.</p>
