从myfaces 1.1迁移到1.2

标签： jsf jsf-1.2 myfaces

我正在尝试将我的Web应用程序从myfaces 1.1升级到1.2。我希望它比直接迁移到最新的2.x版本更容易。但是，当我尝试启动应用程序时，我遇到了这样的错误：

SEVERE: StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

在应用程序日志中可以观察到这样的异常：

＆lt; web-app＆gt;标签已从“2.4”更新为version =“2.5”。我已经尝试用原始的javax.faces.webapp.FacesServlet替换我们的委托servlet（EvoFacesServlet），但没有成功。

servlet容器是Tomcat 6.

我还应该做些什么才能让它发挥作用？

答案 0 :(得分：0)

从部署中删除与容器相关的jar有助于：servlet-api.jar，el-api.jar，jsp-api.jar。不确定其中哪一个是问题的根源。
