Question

我正在将JSF 1.2应用程序迁移到JSF 2.x.我的应用程序使用以下API：

maven-jetty-plugin（版本6.1.10）
maven-compiler-plugin（版本2.3.1）
myfaces-api＆amp; -impl（版本1.2.7）
jsf-facelets（版本1.1.14）
richfaces（版本3.3.3）
javax servlet jstl（版本1.2）
javax servlet-api（版本2.5）
以及其他一些插件。

我更新了faces-config.xml文件中的版本并删除了Facelets 1.1.14库，并用JSF 2.x库替换了MyFaces 1.2，但应用程序无效。它引发了以下例外：

java.lang.ClassNotFoundException：org.apache.myfaces.webapp.StartupServletContextListener

正如包名称提示的那样，这是一个特定于MyFaces的类，当你用Mojarra 2.0而不是MyFaces 2.0替换MyFaces 1.2时，它显然不再可用。

此类通常在webapp的<listener>中被引用为web.xml条目。如果您从<listener>中删除整个web.xml条目，则此异常应该消失。您通常不需要自己明确声明一个，因为它已在TLD文件中注册。但是，Jetty有一些错误，你需要自己明确注册。对于Mojarra来说，那将是：

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

另一种方法是升级到MyFaces 2.0而不是Mojarra 2.0。那边有同一个听众类。

将JSF 1.2迁移到2.x会导致com.sun.faces.config.InitFacesContext.cleanupInitMaps中的java.lang.NullPointerException
