primefaces配置问题
|
我是Primefaces的新手。我尝试使用Primefaces创建示例页面。但是出现以下错误。请帮助我解决此问题。
我的代码是：
<%@page contentType=\"text/html\" pageEncoding=\"UTF-8\"%>
<%@ taglib uri=\"http://java.sun.com/jsf/html\" prefix=\"h\"%>
<%@ taglib uri=\"http://java.sun.com/jsf/core\" prefix=\"f\"%>
<%@ taglib uri=\"http://richfaces.org/a4j\" prefix=\"a4j\"%>
<%@ taglib uri=\"http://richfaces.org/rich\" prefix=\"rich\"%>
<%@ taglib uri=\"http://primefaces.prime.com.tr/ui\" prefix=\"p\" %>
