标签： java jsf-2 jboss

我的开发环境是JBoss 5.1.0 + JSF2.0 + RichFaces + Eclipse Indigo。我是JSF的新手。我试图用RichFace集成一个简单的JSF。但仍然无法执行甚至单个JSF页面。请伙计们帮我解决这个问题。

面-config.xml中

<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%><html>
<head>
      <title>RichFaces Greeter</title>
</head>
<body>
      <f:view>
            <a4j:form>
                  <rich:panel header="RichFaces Greeter" style="width: 315px">
                        <h:outputText value="Your name: " />
                        <h:inputText value="#{UserBean.userName}" >
                        <f:validateLength minimum="1" maximum="30" />
                        </h:inputText>
                        <a4j:commandButton value="Get greeting" reRender="greeting" />
                        <h:panelGroup id="greeting" >
                        <h:outputText value="Hello, " rendered="#{not empty user.name}" />
                        <h:outputText value="#{UserBean.userName}" />
                        <h:outputText value="!" rendered="#{not empty user.name}" />
                        </h:panelGroup>
                  </rich:panel>
            </a4j:form>
      </f:view>
</body>
</html>
