推荐答案
JSF 组件根本没有被解析的症状表明 FacesServlet 没有运行.当请求 URL 与 web.xml 中定义的 FacesServlet 的 url-pattern 不匹配时，就会发生这种情况.这意味着 FacesServlet 的 actual url-pattern 根本不是 *.xhtml.您是否正在研究和编辑您认为正确的 web.xml ?是否将正确的 web.xml 与 webapp 一起部署到 servletcontainer 中?
The symptoms of the JSF components not being parsed at all indicates that the FacesServlet hasn't run. This will happen when the request URL doesn't match the url-pattern of the FacesServlet as definied in web.xml. This would mean that the actual url-pattern of the FacesServlet isn't *.xhtml at all. Are you looking into and editing the right web.xml you think you are? Is the right web.xml been deployed with the webapp into the servletcontainer?
