Glassfish and java:comp/BeanManager

I have .war application that I deploy to glassfish. I want to do CDI开发者_如何学Python, so I need to lookup java:comp/BeanManager from my POJO. But it does not work: BeanManager simply not found!

What is wrong?

Do I need to enable CDI in glassfish? Or it works only in .ear files?

thanks.

Do you have an empty beans.xml under WEB-INF folder? Without beans.xml, CDI is not enabled.
