CommandLink navigation doesn't work in JSF_问答_开发者

i wanted to use the navigation-rule feature of my faces-config.xml (JSF 2.0) but I have some problems with it. I have three files (index.xhtml,index2.html,index3.xhtml) and they look like this:

   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">

<f:loadBundle basename="resources.application" var="bundle"/>

<head>
    <title><h:outputText value="#{bundle['welcome.title']}" /></title>
</head>

<body>
<h3>1</h3>
<h:form>

<h:commandButton action="next2" id="nextpagelink" value="Next Link">Next</h:commandButton>
</h:form>
</body>
</html>

(index.xhtml, the others look similar with different actionnames and other h3-field)

My faces-config.xml has the following entries related to navigation-rules:

<faces-config

  </navigation-case>
 </navigation-rule>
</faces-config>

web.xml:

  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>
</web-app>

However when i click on the link in the index.xhtml file nothing happens. I don't get to the next page index2.xhtml as I thought

There are a lot of reasons for commandlink/button navigation not working, the common ones being:

h:form is missing.
h:form is nested inside another h:form.
Validation or conversion error has occurred.

There are more, but that's as far not relevant yet I think. The code in your question is not the actual code. It looks fine and should work fine (if you add the <html> tag with correct xmlns declarations).

If in vain, I suggest to debug the POST request. What JSF phases were entered/executed? What code got executed and what not?
