Apache Felix + Pax Web + Primefaces：ClassNotFoundException FacesServlet答案

【问题标题】：Apache Felix + Pax Web + Primefaces: ClassNotFoundException FacesServletApache Felix + Pax Web + Primefaces：ClassNotFoundException FacesServlet
【发布时间】：2014-03-20 11:03:53
【问题描述】：

我正在尝试使用 pax web (3.0.5) 在 felix 框架 (4.2.1) 上部署一个简单的 primefaces (4.0) testapplicationon。但我总是得到一个 ClassNotFoundException FacesServlet（和 ConfigureListener）。虽然我在 WEB-INF/lib 中有正确的 jar 文件，并且也在 Bundle-ClassPath 中编写了它们。所以，请帮助我。

清单：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: testprime2
Bundle-SymbolicName: testprime2
Bundle-Version: 1.0.0.qualifier
Import-Package: javax.servlet, javax.servlet.http
Bundle-ClassPath: WEB_INF/classes, lib/jstl-1.2.jar, lib/primefaces-4.0.jar, lib/javax.faces.jar
Web-ContextPath: /testprime2
Webapp-Context: /testprime2

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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  <display-name>testprime2</display-name>

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

  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
  </servlet-mapping>

  <context-param>
    <description>State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2</description>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
  </context-param>

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

</web-app>

错误输出：

【问题讨论】：

标签： primefaces classnotfoundexception apache-felix pax-web

【解决方案1】：

我不确定将这些 jsf 包实际打包到包中是否是个好主意。尝试将它们与战争分开，尤其是 lib/jstl-1.2.jar。因为 Pax Web 应该已经提供了这些所需的软件包。

【讨论】：

谢谢，你是对的。这就是问题所在。但现在我已经到了这一点，我从 pax-web- 中的码头服务器收到“javax.servlet.UnavailableException：Servlet 类 javax.faces.webapp.FacesServlet 不是 javax.servlet.Servlet” extender-war 包...虽然 primefaces 的 pax-web 示例也包括 FacesServlet...
