jsf - 登录.xhtml : The requested resource is not available

标签 jsf tomcat jpa primefaces apache-tomee

我在 Eclipse 中创建了一个动态 Web 项目来尝试在 http://www.simtay.com/simple-crud-web-application-with-jsf-2-1-primefaces-3-5-maven-and-jpa/ 上示例的登录部分 我在项目属性中启用的项目方面是:

  • CDI
  • 动态网络模块
  • Java
  • JavaScript
  • JavaServerFaces
  • JPA

作为容器，我使用 TomEE。

当我尝试启动 login.xhtml 页面时，我获得了

HTTP Status 404 - /LAI_pezzi_Login/faces/Login.xhtml

type Status report

message /LAI_pezzi_Login/faces/Login.xhtml

description The requested resource is not available.

Apache Tomcat (TomEE)/7.0.37

TomEE 控制台:

SEVERE: StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

附言在 TomEE 和项目文件中同时拥有库会不会有问题？我被迫这样做，因为当我使用 Tomcat 时，我错过了很多库，我不知道从哪里得到它们，然后我转向了 TomEE

最佳答案

Web 应用程序的运行时类路径一团糟。 Web 应用程序的 /WEB-INF/lib 似乎包含 JSF 和 JPA 库，它们已经由 TomEE 本身作为 Java EE Web 配置文件兼容容器提供。

Tomcat 是一个准系统的 JSP/Servlet 容器，因此不随例如JSF、JPA、EJB 等。这正是您需要手动提供和配置 JSF、JPA、EJB 等以及 Tomcat 的 Web 应用程序的原因。但对于 TomEE(以及 Glassfish、JBoss AS 等)来说，这绝对没有必要，并且只会因为运行时类路径中重复的不同版本库而导致类加载冲突。

摆脱目标容器本身已经提供的 /WEB-INF/lib 中的库。
