Inject CDI Session Bean in Servlet

I'm getting in my project inject (@ Inject) CDI Beans scopes Request and Session in a servlet. The problem is that for session beans CDI I'm not getting that states remain. I try to modify the state of the bea开发者_开发技巧n from my servlet but when I try to recover from a page is as if the servlet had failed to change state. Someone could help me?
