XML名称空间网址不正确.像这样声明一个名称空间:

The XML namespace url is incorrect. Declaring a namespace like so:

xmlns:composite="http://java.sun.com/jsf/composite"

将产生复合组件名称空间，例如<composite:interface>.

Will result in composite component namespace like <composite:interface> for example.

复合组件应位于WEB-INF/resources/[foldername]文件夹中，其中[foldername]是要保留复合组件的文件夹的名称.

Composite components should be in the WEB-INF/resources/[foldername] folder where [foldername] is the name of the folder you wish to keep composite components.

然后，您可以使用以下URL引用该文件夹中的复合组件，并提供您选择的给定名称空间.对于此示例，假设我在以下文件夹WEB-INF\resources\ptc中有一个名为avatarGenerator.xhtml的复合组件.

You can then reference your composite components in that folder with the following url and providing a given namespace of your choice. For this example lets say I have a composite component called avatarGenerator.xhtml inside of the following folder, WEB-INF\resources\ptc.

XML命名空间声明

xmlns:ptc="http://java.sun.com/jsf/composite/ptc"

使用avatarGenerator

<ptc:avatarGenerator attributeone="" attributetwo="">
