I try to recover the constants in my xhtml jsf in using Omnifaces library, but when I run my project I get:
Cannot find type 'fr.epsi.utils.ConstantsPages' in classpath.
Here is my xhtml page :
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:o="http://omnifaces.org/ui">
<o:importConstants type="fr.epsi.utils.ConstantsPages" />
<h:head>
<title>Acceuil</title>
<h:outputStylesheet name="css/style.css"/>
</h:head>
<h:body>
<h:panelGrid columns="3" cellpadding="10">
<h:link value="Home" outcome="#{ConstantsPages.LOGIN_PAGE}" />
</h:panelGrid>
<h:body>
</html>
And my ConstantsPages class :
package fr.epsi.utils;
public class ConstantsPages {
/* GENERAL */
public static final String LOGIN_PAGE = "/General/login";
public static final String LOGIN_CLIENT_PAGE = "/General/loginClient";
public static final String LOGIN_TECHNICIEN_PAGE = "/General/loginTechnicien";
public static final String ACCUEIL_PAGE = "/General/accueil";
}
And the stack trace :
java.lang.IllegalArgumentException: Cannot find type 'fr.epsi.utils.ConstantsPages' in classpath.

You need to make sure that the class file is properly compiled and placed in webapp's runtime classpath. E.g. as /WEB-INF/classes/fr/epsi/utils/ConstantsPages.class inside the WAR.
This exception says that it is not. There's really no other cause. If you're using an IDE, make sure that the class file is inside Java source folder of the web project and that you've cleaned, rebuilt and redeployed the project and restarted the server.
