Hi Lilianne,
The code you posted creates an instance of TestJndi as a member of the
Filter, thus that class is loaded (and static initializers invoked and
InitialContext accessed) before Filter.init() (in fact, before the
Filter class itself is even loaded I believe) and that is the problem.

Either use Tomcat (but be aware that this code is not spec compliant and
thus non-portable, possibly even to later versions of Tomcat) or find a
different design that doesn't rely on this. I'm not sure what you are
trying to accomplish so I don't have any useful suggestions. What you
have described seems very fragile to me though.
