这是我的 demo.xhtml 页面:

<?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">

</h:head>
<h:body>
    <h2>Hello Demo Portlet!!!!</h2>

    <h3 style="margin-top:0">Client</h3>
    <p:clock />




</h:body>
</html>

当我在不使用标签的情况下将它部署到门户页面时，它工作正常。但是当我添加标签时。

demo.xhtml(带)

<?xml version="1.0" encoding="UTF-8"?>

 <h:form>
 <h2>Hello Demo Portlet!!!!</h2>

 </h:form>


</h:body>

我收到以下错误:

上面提到的是堆栈跟踪。

最佳答案

java.lang.UnsupportedOperationException at javax.faces.context.ExternalContext.getClientWindow(ExternalContext.java:1500)

ExternalContext#getClientWindow()自 JSF 2.2 以来是新的。当您将 JSF 2.2 API 与较旧版本的实现或缺少此方法的组件库一起使用时，您将遇到此异常。

您需要将 Liferay portlet bridge 升级到 JSF 2.2 兼容版本，或者将 JSF 降级到与 Liferay portlet bridge 匹配的版本，例如 JSF 2.1。

关于jsf - java.lang.UnsupportedOperationException 在 javax.faces.context.ExternalContext.getClientWindow(ExternalContext.java :1500)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29339659/
