Ok, i solved it !! first of all i set classloader of my server instance to PARENT_LAST + restart. Then i followed these steps: 1) put Mojarra lib into simple shared library; 2) deploy ear with jsf web module inside and before start application from console, i linked shared lib to it and to all modules inside ear; 3) i set application classloader to PARENT_LAST; 4) start app and it works !!
That's all !!
