Question

我注意到在尝试设置在jetty上运行的JSF 2 webapp时，我有这样的错误：

java.lang.IllegalStateException：应用程序不正确在启动时初始化，找不到Factory： javax.faces.context.FacesContextFactory

可以通过将其添加到我的web.xml

轻松解决

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

我试图寻找详细的解释，但是徒劳无功..

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

这是我的maven依赖：

<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"

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

这是jetty插件的输出：

有什么想法吗？

Answer 1

此侦听器是因为JSF 1.x应该由jsf_core.tld标记库定义文件自动注册。您可以在JSF实现JAR文件的/META-INF文件夹中找到它。对于Mojarra 2.1.3（您似乎根据日志使用），侦听器从第80行开始按如下方式注册：

<!-- ============== 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，Jetty显然没有正确选择。我还读过某个地方，当{<1}}在之前已经初始化 TLD文件被处理之后，你也会得到这个例外。也许这发生在码头。要排除其中一个，请尝试删除FacesServlet条目，以便在处理完TLD之后，仅在第一个具体的HTTP请求中加载它。无论如何，在<load-on-startup>中明确注册监听器确实应该解决它。

此外，由于JSF 2.x，除了TLD文件之外，侦听器也应该由JAR文件中的ServletContainerInitializer实现自动注册，以便解决Glassfish 3错误。在Mojarra 2.x中，这是web.xml类，从第131行开始有以下行：

com.sun.faces.config.FacesInitializer

这仅适用于Servlet 3.0容器，例如Tomcat 7，Glassfish 3，Jetty 8（据称！）等。您似乎使用的是Jetty 8.0，因此它应符合Servlet 3.0，但您的// 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);是声明符合Servlet 2.5，因此容器将以Servlet 2.5回退模式运行。将web.xml更改为符合Servlet 3.0应触发此初始化程序。

Answer 2

还有一个决心：我使用来自wsdl的CXF动态创建了java文件后出现此错误。

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

CXF将自己的ClassLoader（URLClassLoader的实例）放入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作为密钥缓存。由于ClassLoader已更改，因此会创建一个无法初始化的新FactoryManager，因为在原始FactoryManager启动时会删除实现实例列表。因此，找不到Implementation类，因此抛出了IllegalStateException。

解决方案：在CXF的createClient之前备份原始的ClassLoader，将URLClassLoader保存在变量中并将原始的ClassLoader放回Thread。如果要从CXF访问动态类，请通过放入变量的URLClassLoader进行搜索。

我的项目遇到了这个问题，其中包括两个jar文件到lib文件夹，现在我的问题就解决了。谢谢

com.sun.faces：jsf-api：2.2.9 com.sun.faces：jsf-impl：2.2.9

找不到Factory：javax.faces.context.FacesContextFactory
