Question

总之，当我在GL-Server（4.1）上部署我的JSF项目时，我收到消息：警告：此页面调用以前缀p声明的XML名称空间http://primefaces.org/ui，但该名称空间不存在taglibrary

http://s29.postimg.org/km7nd8b47/primefaces.png

我几乎尝试过：创建一个新项目，删除GL-Server，重新安装Maven，用eclipse清理项目等等。

我相信我的项目中必定存在配置错误。一开始一切正常，但后来发生了这个错误。我可以通过创建一个新项目来解决它一段时间，但错误又来了（是因为我在项目方面或其他方面选择了JPA？）

这是我的pom.xml

感谢您的回答。如果您需要更多信息，请告诉我。

Answer 1

看起来缺少Primefaces的依赖项。在@OneToOne( optional = true, cascade = CascadeType.ALL, fetch = FetchType.EAGER) @JoinColumn( name = "current_child_id", nullable = false ) @ForeignKey( name = "FK_parent_child" ) private Child currentChild;：

中添加以下内容

pom.xml

Answer 2

这是部署问题。创建项目后，将其添加到index.xhtml页面xmlns:p="http://primefaces.org/ui" 右键单击项目＆gt; 属性＆gt; 框架添加＆gt; Java Server Faces ＆gt; 在“组件”标签上，选择“Primefaces”＆gt;的确定

右键单击项目，然后选择依赖于构建

尝试一下
