[jcifs] Problem with NtlmServlet

Fri Jun 13 08:17:08 EST 2003

I have read the NtlmServlet code.  It only overrides 2 methods, init() and 
service().  I override init(), but then immediately call the super.init() to 
guarantee that the parent class' init is being executed.

If you have a working example, I'd like to see it.

thanks
