Question

我目前正在使用EJB 3.1，JSF 2.0，mySQL，Netbeans开发Java-EE项目。

我在.xhtml中创建了我的模板，但是当我编译时，我得到了这个警告：

Warning: This page calls for XML namespace declared with prefix div but no taglibrary exists for that namespace.  
Warning: This page calls for XML namespace declared with prefix h3 but no taglibrary exists for that namespace.  
Warning: This page calls for XML namespace declared with prefix div but no taglibrary exists for that namespace.  
Warning: This page calls for XML namespace declared with prefix p but no taglibrary exists for that namespace.

以下是 template.xhtml 的代码（您可以看到我已经包含了所需内容）：

我错过了什么吗？我在我的项目中包含了JSF库..

Answer 1

您是否拥有正确的maven依赖关系？如果它是一个非maven项目将其转换为maven，它将为您解决所有问题。我稍后会发布正确的依赖项。如果有人不是第一个： - ）

JPA EJB CDI JMS（java ee）使用Maven或类似内容的最佳实践

JavaEE此页面调用XML命名空间，但该命名空间不存在taglibrary
