我正在使用 JBoss AS 6、Richfaces 4 和 JSF 2.0。
我开发了一个简单的 xhtml 页面来定义我的布局
这里是 ：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich">
<rich:layout>
<rich:layoutPanel position="top">
Top
</rich:layoutPanel>
<rich:layoutPanel position="right">
Right
</rich:layoutPanel>
<rich:layoutPanel position="center">
Center
</rich:layoutPanel>
<rich:layoutPanel position="left">
Left
</rich:layoutPanel>
<rich:layoutPanel position="bottom">
Bottom
</rich:layoutPanel>
</rich:layout>
</ui:composition>
我在构建路径中添加了这些 jar：
jsf-api.jar
jsf-impl.jar
richfaces-components-api-4.1.0.Final.jar
richfaces-components-ui-4.1.0.Final.jar
richfaces-core-api-4.1.0.Final.jar
richfaces-core-impl-4.1.0.Final.jar
guava-r09.jar
cssparser-0.9.5.jar
sac-1.3.jar
但不幸的是，当我发布时，我收到了这个错误：
