This may not be your problem, but I've seen the same missing web.xml problem
before when trying to deploy and startup after a failed undeploy. The undeploy
failed because one of my webapp files in the Tomcat directory was locked and
couldn't be deleted (either by me in a text editor, or sometimes
I'm not sure what webapps/Root/WEB-INF/web.xml has to do with anything,
but the complaint of a missing web.xml is in context /LoginAction, as
well as another more severe complaint about opening an input stream for
the validation rules xml file. Did you do a soft link or shortcut?
Don't think
