找不到工厂：javax.faces.context.FacesContextFactory - 使用嵌入式 glassfish 3.0

Question

我正在尝试使用嵌入式 glassfish 3.0 运行一个简单的 jsf-2.0 教程，但不断收到此错误。一直在这个论坛和互联网上寻找解决方案，但似乎一无所获。这是 pom：

Web.xml：

<!-- Faces Servlet -->
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Faces Servlet Mapping -->
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

<!-- explicitly setting the EL factory, otherwise is not working correctly under tomcat and jetty    -->
<context-param>
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>

<!-- welcome file mapping -->
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

运行 mvn package 后，会生成 war 文件并启动 glassfish。但抱怨错误。在项目文件夹中，我可以看到 jsf Maven 依赖项：jsf-api-2.1.jar。

谢谢， 莎拉

Answer 1

我会回答我自己的问题。 :P

我将其添加到 web.xml 并工作：

<监听器类>com.sun.faces.config.ConfigureListener

这是解释问题的网页：http://javawords.com/2009/06/05/using-jsf-12-with-facelets-on-google-app-engine-for- java/

看来嵌入的 glassfish 不会在启动时初始化 servlet，而是将初始化推迟到第一个请求。
