I've already asked this question on the Icefaces forum, but meanwhile I realized that this is a more generic problem.

I'd like to update parts of a JSF page when I get a message in my MDB.

The problem is, how do I get the FacesContext from the EJB container?

In the message processing function FacesContext.getCurrentInstance() returns null.

I've also tried to make a JSF managed bean be a MDB, but I couldn't (it seems you can't have both in the same class?).

Since I'm a beginner in the JSF world I'm kind of stuck now. Is there a way to make it work?

(Glassfish v3 + Netbeans 6.8, JSF2 + Icefaces 2.0 alpha2)
