We are trying the main application to access the common Facelets files from shared library deployed in WebLogic.
The common Facelets files are in the below path in shared library:
META-INF->resources->common-ac->HelloWorld.xhtml
We access this in main application page as:
<ui:include src="/common-ac/HelloWorld.xhtml" />
However, this didn't work, it throws the following exception:
javax.faces.view.facelets.TagAttributeException: /....public/Home.xhtml @47,50 <ui:include src="/common-ac/HelloWorld.xhtml"> Invalid path : /common-ac/HelloWorld.xhtml
at com.sun.faces.facelets.tag.ui.IncludeHandler.apply(IncludeHandler.java:125)
How is this caused and how can I solve it?
Using JAR's /META-INF/resources as a shared webapp resource is only supported since Servlet 3.0. So as long as you deploy your webapp to a Servlet 3.0 compatible container (e.g. WebLogic 12) with a web.xml which is declared conform Servlet 3.0 specification, then it should just work out the box.
If you're however deploying your webapp to a non-Servlet 3.0 container (e.g. WebLogic 11 or older), or somehow can't declare your web.xml conform Servlet 3.0 spec, or the target container exposes a bug as to resource resolving from JARs (e.g. early JBoss 6 versions), then you'd need to create a custom Facelets resource resolver as detailed in this answer: How to create a modular JSF 2.0 application?
