Answer 1

Need to changed the weblogic-application.xml of the ear project to

    
        org.opensaml.*
        org.slf4j.*
        antlr.*        
    
    
        javax.faces.*
        com.sun.faces.*
        com.bea.faces.*
        META-INF/services/javax.servlet.ServletContainerInitializer
        META-INF/services/com.sun.faces.spi.FacesConfigResourceProvider
    

Follwoing jar version numbers must match exactly:

• javax.faces-2.x.x.jar
• jsf-api-2.x.x.jar
• jsf-impl-2.x.x.jar
