JSP library using JSF

[Javoso Torso]

Hello,

I am trying to use something like

<logic:empty> (Struts)

in a JSF project, doing

<c:if test="${empty sessionScope.myBean.myProperty}"> (JSP)

I wonder if there is a JSF tag for it...


Which library do I have to include to use the JSP version?
It is not working yet...

is "sessionScope" ok?

Thanks
