probems getting the remote ip address in a bean

[Hansjörg Meuschel]

Hello,
in a bean, how can I extract the IP adress of a user?
I tried

       HttpServletRequest request = 
(HttpServletRequest)((ServletContext) 
FacesContext.getCurrentInstance().getExternalContext().getRequest());
       String IP = request.getRemoteHost();       

but whatever I did I got

       java.lang.ClassCastException: 
com.sun.faces.context.MyHttpServletRequestWrapper

Any ideas? Thanks a lot... Hans
