我使用primefaces库,这是我的jsp页面来源:primefaces调查标签不起作用
<%@taglib uri="http://primefaces.prime.com.tr/ui" prefix="p"%>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<f:view>
<head>
<p:resources />
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
</head>
<body>
<h:form>
<h:outputText id="txt_count" value="#{counterBean.count}" />
<p:poll actionListener="#{counterBean.increment}" update="txt_count" />
</h:form>
</body>
</f:view>
</html>
和我的背豆代码:
import javax.faces.event.ActionEvent;
public class CounterBean {
private int count;
public void increment(ActionEvent actionEvent) {
count++;
}
//getters and setters
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
}
我的web.xml文件中如下

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

我的页面正确加载,但没有正式更新
当它被加载它说“雅虎没有定义”,所以它不起作用。
我已经定义了资源servlet,但它不工作!
请帮帮我!
