在JBOSS上配置MyFaces的实现

在JBOSS上 JSF的默认实现是SUN的RI，要把他替换成Myfaces需要：

1.移除JBoss的现有的JSF实现RI
  修改JBOSS_HOME下的server\<config-name>\deploy\jboss-web.deployer\conf \web.xml文件，把JSF的监听器注掉，并删除jboss-web.deployer 目录下的jsf-libs文件夹

   <!-- Comment/Remove this -->
   <!-- Configures JSF for a web application if the javax.faces.webapp.FacesServlet is declared -->
   <!-- in web.xml.                                                                             -->
   <!--
   <listener>
     <listener-class>org.jboss.web.jsf.integration.config.JBossJSFConfigureListener</listener-class>
   </listener>
   -->
   <!-- Comment/Remove this -->
   <!-- Listens to all web app lifecycle events so that @PreDestroy can be called on -->
   <!-- JSF managed beans that go out of scope.  You can comment this out if you     -->
   <!-- don't use JSF or you don't use annotations on your managed beans.            -->
   <!--
   <listener>
     <listener-class>com.sun.faces.application.WebappLifecycleListener</listener-class>
   </listener>
   -->

2.安装Myfaces的JSF实现

在jboss-web.deployer 目录下新建myfaces-libs文件夹，并把myfaces的实现jar包拷贝到里面

    commons-beanutils.jar
    commons-digester-1.6.jar
    commons-el.jar
    commons-lang-2.1.jar
    myfaces-api.jar
    myfaces-impl.jar

在jboss-web.deployer\conf\web.xml中添加myfaces的监听器

  <listener>
    <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
  </listener>

3.修改jboss-web.deployer\conf\web.xml中JSF相关的init-param参数，替换
    <init-param>
     <description>JSF standard tlds</description>
     <param-name>tagLibJar0</param-name>
     <param-value>jsf-libs/jsf-impl.jar</param-value>
   </init-param>
   <init-param>
     <description>JSTL standard tlds</description>
     <param-name>tagLibJar1</param-name>
     <param-value>jstl.jar</param-value>
   </init-param>

为

    <init-param>
     <description>MyFaces tlds</description>
     <param-name>tagLibJar0</param-name>
     <param-value>myfaces-libs/myfaces-impl.jar</param-value>
    </init-param>

现在启动JBOSS就可以看到加载的已经加载了Myfaces的JSF。
