Java – JSF 2.1.0 not found 13 custom component: tag library supports namespace: but no tag is defined for Name:

problem

I am using JSF 2.1 Create a prototype to demonstrate the benefits of JSF to the webapp we currently build using JSP and struts 1.1 I use JSF 2.2 6 code tracking code, but once I find that Oracle Weblogic 12C does not support JSF 2.2, I have to downgrade Use 2.1 13 the following error was received while running the code:

/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

Google search only points to my bug about nested composite components, but that's not what I'm doing

Solution

After digging many times, I found the cause of my mistake Please note the location of my component: 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 allow location configurable, and I'm on the web XML contains the following:

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

That's why things work in JSF 2.2

The fix for my situation is to delete javax faces. WEBAPP_ RESOURCES_ Directory because it is not used in JSF 2.1 and moves resources to the root
