JSF debugging / JSF newsgroup

Sebastian Fey · Apr 7, 2006

hi there,

actually im looking for a JSF newsgroup.

maybe someone here is able to answer my question:

how do i debug jsf?
or: how do i get the real root cause of an error, ie a bean or a jsp?

a stacktrace like this isnt very helpful, or am i missing sth?
