Question

我在openshift上开发了第一个应用程序。它是一个具有数据库连接性的jsf应用程序。首先，我尝试了一些jsf xhtml页面，没有jpa，所有的工作。当我插入一个bean来访问数据库时，我收到来自服务器的消息＆＃34;部署失败./ROOT.waer。准确地说，当我插入此代码时出现问题：

视图意图的类

 @ManagedBean(name="utnavctrl" ,eager=true)
@SessionScoped
public class Utnavctrl {
    boolean newrecord=false;
    @EJB
    private Usersdao usersdao;
public Utnavctrl(){

数据库连接的bean类

    @Stateless
@LocalBean
public class Usersdao {
    @PersistenceContext(unitName = "primary")
    private EntityManager em;

    public Usersdao() {
        // TODO Auto-generated constructor stub
    }
    public List<User> getAllUsers() {
                return em.createNamedQuery("User.findAll", User.class)
                    .getResultList();
            }

我无法理解为什么在添加这两个类之后（不修改视图方面xhtml ecc）程序不再起作用了。

persince.xml是

 <?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
   xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="

        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
   <persistence-unit name="primary">
      <!-- If you are running in a production environment, add a managed 
         data source, this example data source is just for development and testing! -->
      <!-- The datasource is deployed as WEB-INF/kitchensink-quickstart-ds.xml, you

      <properties>
         <!-- Properties for Hibernate -->
         <property name="hibernate.hbm2ddl.auto" value="create-drop" />
         <property name="hibernate.show_sql" value="false" />
      </properties>
   </persistence-unit>
</persistence>

bean.xml是

    <?xml version="1.0" encoding="UTF-8"?>
<!-- This file can be an empty text file (0 bytes) -->
<!-- We're declaring the schema to save you time if you do have to configure 
   this in the future -->
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee 
        http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
</bean

有人能帮助我吗？

删除eager = true，因为这会给OpenShift带来问题......我不知道为什么，但我已经看到了。
