test.jsp

我的页面加载正确，但没有定期更新

当它被加载时，它说“雅虎没有定义”，所以它不工作

我已经定义了资源servlet，但它还不能工作

请帮帮我

显然，您正在JSF2.0上使用PrimeFaces2.0。在JSF2.0中，

p:resources

已被弃用。您应该使用Facelets而不是JSP。如果一切正常，您应该在服务器日志中看到以下条目：

INFO: p:resources component is deprecated and has no use in PrimeFaces 2.0 as JSF 2.0 resource apis are used instead to place resources on page. 在阅读JSF书籍/教程时，请确保您阅读的是JSF2.0，而不是1.x

INFO: p:resources component is deprecated and has no use in PrimeFaces 2.0 as JSF 2.0 resource apis are used instead to place resources on page.
