How to get servlet context name in a Portlet

[Ignacio de Cordoba]

Hi there,
After some time developing struts2 and JSF(2) I am entering the wonderful world of portlet programming (!!). I need to get the servlet context name in a group of portlets (I need to lookup some stateless session beans). I think there is still no CDI in the Portlet world (hope I am wrong, please tell me if so) and I must do traditional JNDI lookup.
As I am using EJB 3.1, my Session Beans portable names depend on the application name, so I need to getit. I haven't found any PortalContext.getServletContextName() or similar method, so any help will be appreciated (of course, I can read a parameter in web.xml, but I'd like to avoid it as the info I need is just the servlet context (application) name.

Thanks for any info or directions and, or course, sorry if I'm asking something toooo simple,
Ignacio
