It means that there is no logger defined for the admin server, if you want
to enable logging on the admin server, you just have to edit
admin-server.props
and add
org.w3c.jigsaw.logger=org.w3c.jigsaw.http.ExtendedCommonLogger
or just CommonLogger

is it jigadmin or jigadmin 2.0 (the swing version?)
It means that you access attributes of a resource that is no longer
available, maybe you removed the parent using another window.
Can you give me more context information?
