Question

大家好:)我是JSF（2.3）和MyFaces.I的新手。我使用Eclipse。我正在使用以下JAR：

MyFaces的-API-2.3.0.jar
MyFaces的-IMPL-2.3.0.jar

而不是Mojarra。

我的问题始终是当我启动我的tomcat服务器并运行我得到的项目时此错误：enter image description here

    This parameter tells MyFaces if javascript code should be allowed in
    the rendered HTML output.
    If javascript is allowed, command_link anchors will have javascript code
    that submits the corresponding form.
    If javascript is not allowed, the state saving info and nested parameters
    will be added as url parameters.
    Default is 'true'</description>

    If true, rendered HTML code will be formatted, so that it is 'human-readable'
    i.e. additional line separators and whitespace will be written, that do not

    If true, a javascript function will be rendered that is able to restore the
    former vertical scroll on every request. Convenient feature if you have pages
    with long lists and you do not want the browser page to always jump to the top
    if you trigger a link or button action that stays on the same page.

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>

那我错了什么？有人有想法吗？哦，我后来使用Myface Core来使用Myface Tomahawk。

你错过了一种依赖。我建议你使用maven或其他依赖管理器和手工干扰罐进入你的应用程序。
