我注意到在尝试设置在码头上运行的 JSF 2 webapp 时，我遇到了这个错误：

java.lang.IllegalStateException：应用程序在启动时未正确初始化，找不到工厂：javax.faces.context.FacesContextFactory

这很容易通过将它添加到我的 web.xml 来解决

<listener>
    <listener-class>
        com.sun.faces.config.ConfigureListener
    </listener-class>
</listener>

我试过寻找详细的解释，但徒劳无功..

jetty-maven-plugin:8.0.3.v20111011:run + jdk 7 + eclipse indigo

这是我的 Maven 依赖项：

<dependencies>
    <dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.1.3</version>
        <scope>compile</scope>
    </dependency>
</dependencies>

这是我的 web.xml ：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

        </listener-class>
    </listener>

        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
</web-app>

这是码头插件的输出：

有什么想法吗 ？

此侦听器自 JSF 1.x 起应该由jsf_core.tld标记库定义文件自动注册。您可以在/META-INFJSF 实现 JAR 文件的文件夹中找到它。对于 Mojarra 2.1.3（您似乎正在根据日志使用），侦听器从第 80 行开始注册如下：

<!-- ============== Configuration Listener ============== -->

<!--
      This ServletContextListener initializes the runtime environment
      of the JavaServer Faces Reference Implementation when a web
      application including it is initialized by the container.
-->
<listener>
   <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

然而，这显然没有被 Jetty 正确接收。我还在某处读到，当在处理 TLD 文件之前FacesServlet初始化，那么你也会得到这个异常。也许这发生在码头。要排除一个和另一个，请尝试删除该条目，以便仅在处理 TLD 之后很久的第一个具体 HTTP 请求时加载它。无论如何，显式注册监听器确实应该解决它。<load-on-startup>web.xml

此外，由于 JSF 2.x，除了 TLD 文件之外，还应该由ServletContainerInitializerJAR 文件中的实现自动注册侦听器，以解决 Glassfish 3 错误。在 Mojarra 2.x 中，这是com.sun.faces.config.FacesInitializer从第 131 行开始的具有以下行的类：

// The following line is temporary until we can solve an ordering
// issue in V3.  Right now the JSP container looks for a mapping
// of the FacesServlet in the web.xml.  If it's not present, then
// it assumes that the application isn't a faces application.  In this
// case the JSP container will not register the ConfigureListener
// definition from our TLD nor will it parse cause or JSP TLDs to
// be parsed.
servletContext.addListener(com.sun.faces.config.ConfigureListener.class);

这仅适用于 Servlet 3.0 容器，例如 Tomcat 7、Glassfish 3、Jetty 8（据说！）等。您似乎使用的是 Jetty 8.0，因此应该符合 Servlet 3.0，但您web.xml被声明符合 Servlet 2.5，因此容器将以 Servlet 2.5 后备模式运行。更改您web.xml以符合 Servlet 3.0 应该会触发此初始化程序。

另一个解决方法：在我使用 wsdl 中的 CXF 动态创建 java 文件后出现此错误。

JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();
Client client = factory.createClient(wsdlURL, serviceName);

CXF 将它自己的 ClassLoader（URLClassLoader 的实例）放到 Thread 的类加载器中。它以正常方式工作，直到用户的线程进入 JSF 的 FactoryFinder，它由 ClassLoader 作为键缓存。因为 ClassLoader 发生了变化，所以创建了一个新的 FactoryManager，无法初始化，因为在原来的 FactoryManager 启动时，实现实例列表被移除了。因此，找不到实现类，因此抛出 IllegalStateException。

解决方法：在CXF的createClient之前备份原来的ClassLoader，把URLClassLoader保存在一个变量中，然后把原来的ClassLoader放回Thread。当您想从 CXF 访问动态类时，请通过您放入变量的 URLClassLoader 搜索它。

我在我的项目中遇到了这个问题，其中包含两个 jar 文件到 lib 文件夹现在我的问题解决了。谢谢
