找不到工厂:javax.faces.context.FacesContextFactory [英] could not find Factory: javax.faces.context.FacesContextFactory
问题描述
我注意到，当尝试设置在码头上运行的JSF 2 webapp时，出现此错误:
I notice that when trying to setup my JSF 2 webapp running on jetty, i have this error :
java.lang.IllegalStateException:应用程序未正确 在启动时初始化，找不到工厂: javax.faces.context.FacesContextFactory
java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.context.FacesContextFactory
通过将其添加到我的web.xml中很容易解决
which is easily solved by adding this to my web.xml
<listener>
<listener-class>
com.sun.faces.config.ConfigureListener
</listener-class>
</listener>
我试图寻找详细的解释，但徒劳无功..
I've tried searching for a detailed explanation but in futile ..
jetty-maven-plugin:8.0.3.v20111011:run + jdk 7 + eclipse indigo
jetty-maven-plugin:8.0.3.v20111011:run + jdk 7 + eclipse indigo
这是我的Maven依赖项:
And here's my maven dependency :
<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:
Here's my web.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

这是码头插件的输出:

有什么想法吗?
推荐答案
此侦听器是由于JSF 1.x应该由jsf_core.tld标记库定义文件自动注册的.您可以在JSF实现JAR文件的/META-INF文件夹中找到它.如果使用Mojarra 2.1.3(您似乎正在根据日志使用它)，则从第80行开始按以下方式注册侦听器:
This listener is since JSF 1.x supposed to be automatically registered by the jsf_core.tld tag library definition file. You can find it in the /META-INF folder of the JSF implementation JAR file. In case of Mojarra 2.1.3 (which you seem to be using according the logs), the listener is registered as follows from line 80 and on:
<!-- ============== 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>
但是，Jetty显然没有正确地处理此问题.我还在某处读到，当在处理TLD文件之前 初始化FacesServlet时，您也会得到此异常.也许这发生在码头.要排除一个和另一个，请尝试删除<load-on-startup>条目，以便仅在处理TLD之后很久才在第一个具体的HTTP请求上加载该条目.无论如何，在web.xml中显式注册侦听器确实可以解决该问题.
However, this is apparently not been picked up properly by Jetty. I've also read somewhere that when the FacesServlet is been initialized before the TLD file is been processed, then you will also get exactly this exception. Perhaps this is happening in Jetty. To exclude the one and other, try to remove the <load-on-startup> entry so that it will be loaded only on first concrete HTTP request, far after the TLD is been processed. In any way, explicitly registering the listener in web.xml should indeed solve it.
Further, since JSF 2.x, in addition to the TLD file, the listener is also supposed to be automatically registered by a ServletContainerInitializer implementation in the JAR file in order to workaround a Glassfish 3 bug. In Mojarra 2.x this is the com.sun.faces.config.FacesInitializer class which has the following lines starting at line 131:
// 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.您似乎正在使用Jetty 8.0，因此应符合Servlet 3.0，但您的web.xml声明为"conform" Servlet 2.5，因此该容器将以Servlet 2.5后备方式运行.更改您的web.xml以符合Servlet 3.0应该会触发此初始化程序.
This works in Servlet 3.0 containers only, such as Tomcat 7, Glassfish 3, Jetty 8 (supposedly!), etc. You seem to be using Jetty 8.0 which should thus comply Servlet 3.0, but your web.xml is declared conform Servlet 2.5, so the container will run in Servlet 2.5 fallback modus. Changing your web.xml to conform Servlet 3.0 should trigger this initializer.
