我正在创建我的第一个项目Java EE 7,但我遇到了麻烦.感谢任何帮助.
应用程序启动时,Tomcat日志显示以下消息:
"validateJarFile (C:\...\build\web\WEB-INF\lib\javaee-api-7.0.jar)-jar not loaded. See Servlet 2.3 Spec, section 9.7.2. Offending class: javax/servlet/Servlet .class"
当我点击调用托管bean的按钮时,我收到错误:
Advertência: /index.xhtml @18,66 value="#{indexMB.user}": Target Unreachable, identifier 'indexMB' resolved to null
javax.el.PropertyNotFoundException: /index.xhtml @18,66 value="#{indexMB.user}": Target Unreachable, identifier 'indexMB' resolved to null
IndexMB
@Named("indexMB")
@RequestScoped
public class IndexMB {
private String password;
private String user;
public String loginTest(){
return (this.user.equals("admin") ? "adminPage" : "inOutPage");
}
// getters and setters
}
的index.xhtml
<html ...>
<f:loadBundle …我在tomcat 7上使用Hibernate和Weld CDI运行一个项目.我已经编写了一个ServletContextListener来在应用程序启动期间创建EntityManagerFactory和EntityManager.
public class PersistenceListener implements ServletContextListener {
private static EntityManagerFactory entityManagerFactory;
public void contextInitialized(ServletContextEvent sce){
ServletContext context = sce.getServletContext();
entityManagerFactory = Persistence.createEntityManagerFactory("hibernate-test");
}
public void contextDestroyed(ServletContextEvent sce) {
entityManagerFactory.close();
}
public static EntityManager createEntityManager() {
if (entityManagerFactory == null) {
throw new IllegalStateException("Context is not initialized yet.");
}
return entityManagerFactory.createEntityManager();
}
}
我可以通过以下代码创建它,在我的测试类(它是一个arquillian测试类)中使用我的entityManager
EntityManager em = PersistenceListener.createEntityManager();
em.getTransaction().begin();
em.createQuery("delete from Game").executeUpdate();
em.getTransaction().commit();
这是我的测试类的完整代码
@RunWith(Arquillian.class)
public class HibernateTestSample {
@Deployment
public static WebArchive createTestArchive()
{
MavenDependencyResolver resolver = DependencyResolvers.use( …
