Hi Martynas, you are getting NPE because "request.getRemoteHost()" is
returning null value after you enableLookups! Maybe you have problem
resolving hostname in your env? Try to disable the valve and test "<%=
request.getRemoteHost() %>" in a simple jsp until you can get the right
value before re-enable the valve again.
