pages.xml 是
<page view-id="/secure/admin/update.xhtml" action="#{homePage.getUpdate()}">
<param name="conversationId" value="none" />
</page>
界面是
@Local
public interface HomePage extends Serializable {

public static final String CUSTOMER_HOME_PAGE = "/secure/customer/home.xhtml";

public static final String UPDATE = "/secure/admin/user/updateUser.xhtml";
public String getHomePage();
public String getHome();
public String getUpdate();
