找不到JSF 2.1.13自定义组件：标签库支持命名空间： <namsepace> 但没有为名称定义标签： <compositecomponent>

Question

Problem

I am using JSF 2.1.13 to create a prototype to demostrate the benefits of JSF over our current webapp built with JSP and struts 1.1 . I following code using works with JSF 2.2.6 , but I had to down grade once I found out that Oracle Weblogic 12c doesn't support JSF 2.2 yet. When running the code with 2.1.13 I receive the following error:

/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

Googling only pointed me to a bug about nested composite components , but that isn't something I'm doing.

Code

Answer 1

After more digging I found what caused my error. Note the location of my compontent: webapp/WEB-INF/resources/ccc/codedType.xhtml . The appropriate location should be webapp/resources/ccc/codedType.xhtml (root vs WEB-INF ). In JSF 2.2, they allowed the location to be configurable and I had the following in my web.xml :

<context-param>
  <param-name>javax.faces.WEBAPP_RESOURCES_DIRECTORY</param-name>
  <param-value>/WEB-INF/resources</param-value>
</context-param>

which is why things worked in JSF 2.2.

The fix for my situation was to remove javax.faces.WEBAPP_RESOURCES_DIRECTORY since it isn't used in JSF 2.1 and move the resources to the root.

我最近遇到了这个错误：请确保将模板放在位置src ../ META-INF / resources / myFolder并使用xmlns引用它：tp =“http://java.sun.com/jsf/composite/myFolder” >这帮助我解决了这个问题。
