我正在使用JSF 2.1.13创建一个原型来证明JSF的优势,而不是我们当前使用JSP和构建的webapp struts 1.1.我使用的是代码JSF 2.2.6,但是当我发现Oracle Weblogic 12c还不支持JSF 2.2 时,我不得不降级.使用2.1.13运行代码时收到以下错误:
/pages/sites/tab-details.xhtml @27,90 <ccc:codedType> Tag Library supports namespace: http://java.sun.com/jsf/composite/ccc, but no tag was defined for name: codedType

谷歌搜索只指向我有关嵌套复合组件的错误,但这不是我正在做的事情.

经过多次挖掘后,我发现了导致我错误的原因.注意我的组件的位置:webapp/WEB-INF/resources/ccc/codedType.xhtml.适当的位置应该是webapp/resources/ccc/codedType.xhtml(root vs WEB-INF).在JSF 2.2中,他们允许位置可配置,我在以下内容中有以下内容web.xml:
<context-param>
<param-name>javax.faces.WEBAPP_RESOURCES_DIRECTORY</param-name>
<param-value>/WEB-INF/resources</param-value>
</context-param>

这就是为什么事情在JSF 2.2中有效.
我的情况的修复是删除,javax.faces.WEBAPP_RESOURCES_DIRECTORY因为它没有在JSF 2.1中使用并将资源移动到根.
