This week's book giveaway is in the Spring forum. We're giving away four copies of Pro Spring MVC with WebFlux: Web Development in Spring Framework 5 and Spring Boot 2 and have Marten Deinum & Iuliana Cosmina on-line! See this thread for details.
Let me give you a hint about namespace of a composite.
If your composite markup file is called loginPanel.xhtml and it is inside a folder (resource library) called ezcomp.
The namespace for this composite should be something like xmln:ez="http://java.sun.com/jsf/composite/ezcomp"
